title: Combined effects of Pu-239 Dioxide and Cigarette Smoke on the Production of Lung Tumours in the Mouse
title: Link to data and details in ERA

description: Purpose: To determine whether cigarette smoke and Pu-239 dioxide act synergistically with respect to the production of lung tumours in CBA/Ca mice.

Status: 1987 - 1991, terminated

Treatment: Actinide exposure: single nose-only inhalation of Pu-239 (1.5 m AMAD, 1.2-1.3 g) prepared by calcination of the oxalate at 550oC for 3 hours.

Smoke exposure: Nose-only inhalation of mainstream smoke generated from high-tar un-tipped cigarettes diluted 40-fold with clean air (tar particulate =1.4 mg/l, CO concentration =1000 ppm). Twice-daily 30 minute exposures, 5 days a week for 12 months.

A Dose effect relationship

B Effect of smoking

Dosimetry: Radiochemical analysis to determine Pu239 content of lungs from mice killed at 1, 7, 28, 84, 196 and 364 days post actinide exposure. Trapezoidal method to calculate average radiation dose to lungs.

Endpoints: Terminal sacrifice 18 months after actinide exposure, plus sporadic deaths. Necropsy observation and histopathology of all macroscopically obvious abnormalities. Lungs cleared to determine the absolute number of lung lesions.

Animal: Female CBA/Ca mice 10 weeks of age (approximately 20 g) at time of actinide exposure.

Results: The study failed to demonstrate a synergistic effect on the production of lung tumours following the exposure of CBA/Ca mice to the combined insult of Pu-239 and cigarette smoke. The results did, however, indicate an apparent effect of stress on the tumour frequency, as animals that were sham-smoked also had a lower incidence of lung tumours compared to cage-controls given the same dose of plutonium.

title: Life-span Study of the Induction of Lung Tumours in CBA/Ca Mice by Pu-239 Dioxide
title: Link to data and details in ERA

description: Purpose: To investigate the processes preceding and accompanying Pu-induction of lung tumours in mice and to compare histological and site characteristics of mouse tumours with those in man with a view of evaluating the validity of the mouse lung tumour model.

Status: 1990 - 1993

Treatment: Inhalation Pu-239 dioxide (AMAD 1.5 μm) to give a mean IAD of about 100 Bq (corresponding to the maximal lung tumour incidence). Serial sacrifices of 50 Pu-exposed and 50 sham-exposed mice (including intercurrent deaths) at 8, 12, 16, 20, 24, and 28 months. Remainder killed when moribund. Groups of 4 Pu-exposed mice killed for the assessment of residual Pu in lung.

Dosimetry: Cumulative calculated dose to lung at 24 months is 4.5 Gy.

Endpoints: Macroscopic/microscopic pathology of the lung, and all macroscopically obvious abnormalities.

Animal: Female CBA/Ca mice aged 63 ± 5 days.

Results: Spontaneous incidence of lung tumours in control mice was below 10% up to an age of 20 months and increased with age after this time. Pu-239 exposed mice showed a significant and progressive increase in lung tumour incidence with the difference between control and exposed mice increasing with age. The lung tumours observed in exposed mice were mostly of the bronchiolo-alveolar type; no small cell tumours and, in contrast to rats, no squamous tumours were seen. Studies carried out in parallel in the same strain followed the long-term behaviour of Pu-239 and U-235 dioxide particles in lung.

title: Investigations on the automatic temperature control electronics of the single stage space Stirling-type pulse tube cryocooler.

description: In this paper, the automatic temperature control electronics of single stage space Stirling-type pulse tube cryocooler (SPTC) has been investigated theoretically and experimentally. Pulse width modulation technique is implemented to provide sinusoidal drive to the linear compressor under DC power supply. Digital expert PID control algorithm is applied to provide the temperature control. Mathematical model of the SPTC has been proposed and relevant simulations have been done. The design considerations of the hardware and control software of the electronics are described in detail. The actual control electronics has been worked out and then tested on a typical coaxial SPTC developed in the authors’ laboratory. Experiment shows that the developed automatic temperature control electronics can generate sinusoidal signal under the given DC power supply with the converting efficiency of 95%. And it can also provide the temperature control for the SPTC at 80 K with stability of better than ±0.2 K in 2 hours. With heat load disturbance, the cold temperature stability is better than ±0.3 K.

title: Simulation and experimental validation of the variable refrigerant flows system under the cooling conditions.

description: Variable refrigerant flow (VRF) air conditioning system gains widely attentions due to its better energy performance in the part load conditions. However, the outdoor air ventilation capacity of the VRF system is usually not satisfied. A VRF and variable air volume combined air conditioning system is investigated through simulation as a solution for the ventilation problem while taking advantage of its high part load energy efficiency. In the previous study, VRF models of component-number independence were developed. As another part of the study, this paper introduces the work in the experimental validation of simulation models. Firstly, the experimental rig is introduced, which consists of an outdoor unit (including a variable speed compressor and a heat exchanger), two indoor heat exchangers, two electronic expansion valves, pipes and accessories. A constant temperature and humidity room is used to ensure the required inlet conditions for all the heat exchangers. Secondly, the simulation models are validated using the experimental data. The maximum errors for cooling capacity and input power are less than 7%. The maximum relative error of COP is 10.54%. In addition, the control responses of the VRF system under the various conditions are validated. The results show that simulation matches the experiments very well indicating the accurate prediction of the models responding to the varying compressor speed, EEV opening position and evaporator inlet air temperature.

title: CFD-based correlation development for air side performance of small diameter tube-fin heat exchangers with wavy fins.

description: A great deal of effort is spent on the design and optimization of air-to-refrigerant heat exchangers in HVAC&R applications. One path towards improving their performance is the transition to smaller hydraulic diameter flow channels. In particular, tube diameters below 5mm need to be investigated. The in-tube refrigerant flow characteristics are well understood for small diameter tubes and accurate heat transfer and pressure drop correlations are available in the literature. On the air side, however, most of what is available in the literature has none, or very limited applicability to small tube diameter heat exchangers. In these situations numerical methods such as CFD are commonly employed in the performance evaluation of tube and fin surfaces. This work presents new CFD-based correlations for finned tube heat exchangers with tube diameter ranging from 2mm to 5mm. The methodology implemented in this work consists of analyzing air-side heat transfer and pressure drop characteristics by using Parallel Parameterized CFD (PPCFD. The post-processed data is reduced into correlations that can be easily implemented in various heat exchanger analyses tools. The j and f factors correlations fit, 64% and 66% of the source data respectively, within an error of 20%. As new experimental data becomes available, the correlations will be validated and updated. In the meanwhile, researchers and engineers can use these correlations for evaluating the performance of small tube diameter heat exchangers.

title: Development of humidity measuring device using porous ceramic based on principle of psychrometer.

description: Hot air, both dry and moist, has been widely used for heating and/or a reaction atmosphere in a broad range of industrial fields including food processing, material drying, and other heat treatments. In a process that uses hot air and superheated steam, the gas flow temperature, pressure, and humidity inside the treatment chamber have a major impact on the quality of the finished product. However, there is no simple method of measuring humidity that can be used over an extended duration in applications that use superheated steam at temperatures above 100°C. In this paper, we introduce a device developed for measuring humidity, which consists of a wetted porous ceramic probe with thermocouples, a water retention control system, and computing devices. The measured humidity (steam mole fraction) is calculated from the measured wet- and dry-bulb temperatures using the adiabatic saturation line equation on which we previously reported. The equation was extended to enable its application to temperatures of up to 350°C and a humidity up to that of superheated steam. Accuracy measurements were conducted with a humidity generator and a gas flow temperature of 200°C, a gas flow velocity of 3 m/s, and steam mole fraction ranging from that of hot air to that of superheated steam. The cause of any errors was investigated.

title: Magnetocaloric effect in Nd0.7Sr0.3MnO3: Cuo composites.

description: In this work, the Nd0.7Sr0.3MnO3: CuO composite based on perovskite manganite-oxide have been prepared by solid reaction technology with sintering temperature of 1473 K. The samples are of single phase with orthorhombic structure of Pcmn (62) symmetry. By adding and varying the oxide composition in these compounds, not only the magnetization but also the magnetocaloric properties have been enhanced. From the measurement of isothermal magnetization around the Curie temperature, the maximum isothermal magnetic entropy change was calculated as 5.14 J/Kg.K at 5T for the 95%Nd0.7Sr0.3MnO3+5%CuO composites. Furthermore, a large relative cooling power was about 232 J/Kg. These magnetocaloric properties make Nd0.7Sr0.3MnO3:CuO composites an attractive candidate material for magnetic refrigeration application.

title: Multi-scale analysis and optimization of tube shapes for air-to-refrigerant heat exchangers.

description: Air-to-refrigerant heat exchangers are a key component in heat pumps and refrigeration systems. Literature review shows that significant reduction in material, refrigerant charge and air-side thermal resistance can be obtained by utilizing smaller refrigerant-side hydraulic diameter. While such designs offer some improvement in compactness of the heat exchanger, the air-side resistance is still the dominant resistance. One contributing factor is the shape of the tube itself which is generally limited to a circular or oval profile. This paper describes a comprehensive method for multi-scale analysis and optimization of tube shapes on the air side for novel finless air-to-refrigerant heat exchangers. Bezier curves are employed for tube shape parameterization using a Non-Uniform Rational B-Splines (NURBS) algorithm. Air-side performance is evaluated using CFD in a 2-dimensional periodic computational domain. The method is applied to design a 1.0 kW air-to-water heat exchanger with Parallel Parameterized CFD and Approximation Assisted Optimization techniques. Structural analysis for mechanical stresses and deformation is also carried out. It is shown that the resulting optimum designs can be 50% smaller than compact micro channel heat exchangers with at least 20% better performance.

title: Evaluation of the influence of the subcooling on the performance of vapor injection scroll compressors.

description: In this work, the influence of subcooling in the performance of an injection scroll compressor is analyzed as a function of evaporating and condensing temperature. In order to do that, a test campaign has been developed. The test campaign has included experimental evaporation temperatures from -20°C to 10°C, condensing temperatures from 40°C to 60°C and subcooling from 0°C to 20°C using R407C as refrigerant. The obtained data have been used to determine the influence of the subcooling in cycle efficiency and compressor performance (through the modification of the intermediate pressure injection).Two main results have been obtained from all this work: a) a correlation for the compressor intermediate pressure as a function of the operating conditions, b) The difficulty to control the compressor intermediate conditions with the expansion valve when the subcooling increases. The explanation for this phenomenon has been made in terms of the compressor design in this kind of cycle.

title: Comparative analysis of a vapour-injection scroll compressor and a two-stage reciprocating compressor based on its application range.

description: The current paper presents a comparative analysis of a vapour-injection scroll compressor (SCVI) and a two-stage reciprocating compressor (TSRC) based on its application range. It was conducted in two parts, on the first one; the compressors were compared in terms of COP, economizer capacity, compressor efficiency, and volumetric efficiency, using R407C refrigerant. On the second part, the seasonal performances of both compressors working in cooling and heating modes were analysed. As a result, the SCVI presents better COP and efficiency with pressure ratios below 7; it can be applied for HVAC and air conditioning, systems for refrigerated products up to -15°C like refrigerated transport (reefers). On the other hand, the TSRC performs better with higher pressure ratios (above 7), in applications like: domestic water heating applications at high temperatures (above 60°C), heat pumps for cold regions and refrigeration systems for low temperatures (below -20°C) as ultrafreezing applications and the like.

title: Experiment study on performance of multistage water tanks heat storage applied to solar air conditioning.

description: The system of multistage tanks applied to the solar air conditioning was presented. Above the theoretical analyzing, the system of multistage tanks test-bed has been built to study the performance of the multistage tanks system with different series. The results showed that: the heat storage consuming time of the first-stage tank decreased and the heat storage grade improved with increasing the system series, and the time of ideal heating inlet water temperature increased with increasing the system series, in the heat release period, the conclusion is opposite. According to the above conclusion, the optimization strategy for the system of multistage tanks was proposed, the system after optimization has obvious effect prolonging the time of ideal heating inlet water temperature.

title: Exploring a new heterogeneity index to quantify the variation of cooling rates within systems that undergo the forced-air cooling process.

description: Forced-air cooling is a commonly used pre-cooling process that forces refrigerated air through a stacked pallet of produce, rapidly removing the field heat in preparation for storage and transport. Cooling rates can vary spatially throughout the pallet due to uneven airflow distribution and the relative proximity to the inlet of refrigerated air. This heterogeneity in pre-cooling processes may result in significant differences in quality and shelf life at the end of the cold chain. Therefore in assessing pre-cooling performance, in addition to assessing average cooling rate (through 1/2 cooling or 7/8 cooling time), a robust heterogeneity metric is required to quantify the variability in a cooling process, and hence compare different systems. The aim of this work is to develop this heterogeneity index. The new method is illustrated through application to polylined kiwifruit inside of a modular bulk package.

title: Thermodynamic properties of fluorocarbons: simulations and experiment.

description: We will present our latest research results on the thermodynamic properties of fluorocarbons that are used as unconventional refrigerants within high-tech electronics installations both in particle detectors and in other applications in the electronics industry. The SAFT equations of state were used to model various thermodynamic properties, vapor-liquid phase transition, and equilibrium. Two models were studied and compared in detail: PC-SAFT EoS and Soft-SAFT EoS. Three models were finally implemented in C programming language, since an additional ideal gas model is necessary in order to calculate the ideal gas contributions to the residual thermodynamic properties. A future move towards simulation of binary mixtures is also outlined and studied. A new automated apparatus for speed of sound measurements has been prepared and our own experimental data has been used to verify and evaluate our simulation model results, namely for those regions where no published fluorocarbon experimental data are available. Actual speeds of sound measurements were carried out in two fluorocarbons C3F8 and C2F6 and in a mixture of C3F8 and C2F6. A total of more than 400 new data points along 15 isotherms, with pressures up to 0.5 MPa, were obtained.

title: The AIRCOOLER device - A flexible and mobile cooling solution for lower level heat loads.

description: We will present here a simple cooling device that has already been developed in three variants and is designated to provide a wide range of cooling temperatures with moderate or low heat fluxes (up to hundreds of watts) to be removed. Our new AIRCOOLER uses the principle of Vortex tube cooling. Its special custom design has been adjusted for use in a wide range of temperatures down to -50°C, achieved with a nominal standard air pressure value within the supply lines in most labs and industry facilities at a level of 8 to 9 bar. The simple box-like design using Vortex tubes coupled with some extra heat exchangers has no moving parts and requires only a pressurized dry air supply to provide a cooling effect. It is ideally suited for applications in electronics laboratories and also in applications with a problematic ambient environment (such as strong magnetic field and a high radiation environment).
