Published: April 2021

Abstract
Continuous reduction in the size of the electronics for space limitations with higher processing speed generates high heat flux density from the electronics chips during its operational mode. However, this increased heat flux density causes a major problem for the electronics and leads to the failure of the components if not removed properly. This paper investigates the various cooling techniques especially the liquid cooling system operated with nanofluids-a special kind of fluid with the dispersion of nanometre sized particles. This paper quantifies the various kinds of nanofluids used for electronics cooling along with its thermal performance by targeting on the thermal characteristics such as heat transfer coefficient, thermal resistance, thermal conductance, interface temperature, etc. This paper also quantifies the operation of nanofluids over the various geometries of micro channel heat exchangers that serve as a heat sink for power dissipation from the electronics.

Abstract
Refrigerating compartment with and without shelves is designed for analyzing the air flow and temperature distributions by using the Simulation software Ansys work bench 14. Comparing the results of the air and temperature distributions inside the refrigerating compartment with and without shelves. Here shelves considered as obstacles and the refrigerator without freezer compartment is considered as a 2D rectangular enclosure one side is assumed as evaporator wall (cold wall) and other side as Door (warm wall). Inside the refrigerator cabin air flow takes by natural convection. Temperature distributions is observed in the compartment without shelves and with shelves and same is compared. In the natural convection heat transfer happens between the internal walls of the refrigerator and air by radiation, conduction and convection. Air flows downward near the cold wall and moves upward near warm wall due to the density variation. As a result, temperature stratification was observed in the refrigerating compartment. Evaporator wall maintains the colder region and door wall has the higher temperature.

Authors: Maniarasu R. , Rathore Sushil Kumar , Murugan S. 
Published: April 2021

AbstractThere are three major methods used to capture carbon dioxide (CO2) which include post-combustion, pre-combustion and oxy-fuel combustion method. Post combustion method is a technically and economically possible for CO2capture. Generally, CO2is first separated from a gas stream which contains CO2and then captured. There are three main methods used to separate CO2viz., solvent separation, membrane separation and cryogenic separation. In post combustion, for capturing CO2different techniques such as absorption, adsorption, membrane and cryogenic distillation are used. Adsorption is the most commonly used method for CO2capture. Activated carbon obtained from charcoal is considered as a potential adsorbent material for CO2capture. In this study, potential of using activated carbon obtained from two biomass substances viz., coconut shell and palm shell were examined as the adsorbent materials which would be used to capture CO2. For this purpose, the surface area, porosity, surface morphology and functional groups of the samples of activated carbon chosen for the study were obtained by using Brunauer-Emmet-Teller (BET), Scanning electron microscope (SEM), Thermogravimetry (TGA) and Derivative thermogravimetry (DTG) respectively. The preparation of biomass based activated carbon, adsorption properties and characterization of adsorbents were studied and the results are presented in this paper.

Published: April 2021

Abstract
This article presents a design scheme for a scrubber pertaining to the classes of cleaning devices for washing household utensils. The power scrubber is wall-mounted preferably near a kitchen sink and can be operated with a foot pedal for hand-free operation. The scrubbing device comes with various attachments, which could be used alternatively based on the dishwashing needs. It has been estimated that an average household utilizes almost 50 individual pieces of utensils to cook and serve food items, washing them requires huge amounts of water and is somewhat labour intensive due to the scrubbing action that is necessary to clean utensils. Though there are dishwashing machines available in the market, they are quite bulky and expensive for the common household in India, moreover they consume a lot of power and is not suited for washing single utensils and even has restrictions on the types of utensils to be washed. It has been realized by us that the utensil scrubbing is the most important task in the process. The power scrubber is a wall-mounted scrubber and is also capable of dispensing soap and in-turn reduce water usage.

Published: April 2021

Abstract
The expensive manufacturing process and low efficiency at the high working temperature of photovoltaic cells necessitate the need for an alternate solar energy generation system. In this study, a concentrated solar thermal system that works on the principle of the Seebeck effect has been selected for electical energy conversion. Standard Thermal Electric Generator (TEG) of material Bismuth Telluride is considered for harvesting energy from concentrated solar irradiance. In this research work, a Fresnel sheet concentrator has been used as the concentrating medium due to its low weight and easy installation. The solar simulator experiment is carried out on the Bismuth Telluride TEG module (type TEP1-12656-0.6) to find out its output characteristics curve with respect to irradiance. In this connection, high temperature is maintained at the top of the TEG by using fresnel concentrator and low temperature is maintained at the bottom by utilising the Flow Channel concept. Analysis of the flow channel is done in detail using ANSYS version 15. Results are discussed. Based on this result, the water flow rate has been optimised and it is found that the high temperature at the top of the TEG is not constant due to solar irradient uncertainity. A complete cost analysis is performed and the payback period of the proposed model is found out to be considerably less compared to the conventional solar panel system. Hence, in this manner, the most abundant renewable energy like solar energy is made use efficiently as well as economically, without causing any harm to the environmental well-being.

Authors: Premnath D , Chandrasekaran P , Ganapathy Subramanian L.R 
Published: April 2021

Abstract
The present work investigates the solidification activity of deionized water as phase change material dispersed with various bio-additives such as gelatin and corn starch in a spherical capsule immersed in a constant temperature bath. Tests are carried out at two different bath temperatures (-6°C and -9°C) and it was noted that deionized water undergoes a subcooling of -3.8°C at a bath temperature of -6°C. However, no subcooling is reported for the deionized water with a concentration of 0.1wt.% for both the additives. A maximum reduction of 51% and 45% in total solidification time is observed for gelatin solution at bath temperatures of -6°C and -9°C respectively. A significant reduction of 82% is observed while considering 50% of phase change material(PCM) mass at a bath temperature of -6°C. Hence, it is concluded that reducing subcooling and partial charging of water-based PCMs would help to increase the Cool Thermal Energy Storage (CTES) system’s energy efficiency.

Abstract
A Turbocharger mitigation system was designed for vehicular operations and simulated in lab conditions. In production cars, a huge loss of power is noticed under 1500 rpm which is termed as “turbo-lag”. The effects of turbo lag include increased fuel consumption, lesser efficiency, brake power loss and more emissions. A complete analysis of the existing system was done and the parameters were measured for a wide range of engine rpm. A servo motor actuation system was mated with the turbocharger. The control algorithm and principles were programmed in Arduino software. After successful implementation, the results were compared with the previous setup in MS Excel software.

Authors: Vinoliah E. Melita , Ganesan K. 
Published: April 2021

Abstract
We consider a multi-objective generalized assignment problem in which the costs are fuzzy numbers. The generalized assignment problem has gained its significance in the fuzzy environment. We have represented the fuzzy numbers in their parametric form and then solved it through ones assignment method. To the best of our knowledge, most of the authors have obtained the solution by converting the problem to its crisp form. We have recommended an algorithm where we have used the ranking method and arithmetic operations to obtain a desirable solution without converting to an equivalent crisp form. The solution we acquired is represented in terms of location index and fuzziness index functions which enables the decision maker to decide his/her preference of solution. An example is given to explain the proposed methodology.

Published: April 2021

Abstract
Heat exchangers are devices which are used to transfer the thermal energy between two or more fluids. They are used in various industries for space heating, air conditioning and chemical processing. Some heat exchangers which are experienced in our daily lives include pasteurization, radiators and oil coolers in automobiles Heat exchangers have been divided in several ways, based on its flow direction which are parallel or counter flow, types of construction of the heat exchanger like tubular or plate heat exchanger, the ways of contact between the fluids i.e. direct or indirect.
The heat exchangers performance is usually depending upon the physical characteristics of the fluid and the material. When a concentric tube is added in the intermediate space of a double pipe heat exchanger, we obtain a triple pipe heat exchanger, we obtain a triple pipe heat exchanger. The performance of the triple is better than the double pipe, as it provides better heat transfer efficiencies. Basically, the additional pipe improves the heat transfer by providing an additional flow passage and a larger area for heat transfer area per unit length of the exchanger.

Published: April 2021

Abstract
This examination is planned to research the hardening conduct of water scattered with Graphene nano particles in a circular holder during cementing. The examinations were directed with unadulterated water and nanofluid stage change materials (NFPCMs) with GNP mass grouping of 0.35 %, 0.7 % and 1.05 %. The NFPCM was set up by scattering graphene nanoparticles and a nucleating specialist in the base PCM (stage change material). Nanoparticle’s (GNP) go about as a nucleating specialist to help the quick development of precious stones in cementing processes. The expansion of GNPs came about with an apparent decrease in the sub cooling of water from - 12 °C to - 2.5 °C alongside decrease of 25 % in cementing time attributable to its high warm conductivity and bigger explicit surface region. The expansion of the Nucleating operator lessens the serious situation of sub-cooling in the PCM, all things considered, which improves the exhibition of evaporator in a refrigeration framework. In addition, NFPCM with upgraded heat move rate and without sub-cooling can be valuable in numerous CTES (Cool Thermal Energy Storage) applications. The beginning of hardening progressed on account of NFPCM because of higher cooling rate in the sub cooling district for some random driving potential. The quickened method of vitality charging happened during 78 % of all out cementing time.

Abstract
In recent decades, the construction industry is facing a difficulty arising out of decline in the availability of natural resource material for the preparation of concrete due to depletion. An investigation is carried out on the reuse of waste slag as an alternative material to natural material in concrete production, satisfying relevant international standards. Electric Arc Furnace Slag (EAFS) is a material which is obtained from the steel industry during the production of steel from its raw ore. It can be used as both fine and coarse aggregate in concrete. This paper presents about the usage of EAFS in concrete preparation and results of some tests conducted on it. This study concentrates on 50% replacement of EAFS as coarse aggregate in concrete preparation. The mechanical properties of the EAFS is addressed. The compressive and split tensile strength is analysed for the age of 7, 14 and 28 days. The test results revealed that partial replacement of EAFS as coarse aggregate showed more or less similar results when compared to conventional concrete. Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) techniques are used to study topographic, crystallographic of material and chemical composition of slag and the corresponding results are included.

Abstract
We live in an era where most organizations tend to pay the utmost significance to the customer. Most organizations will position their business models to align with the demands put forth by the customer and hence, better cater them. However, more often than not, these organizations fail to accommodate the individuality of each of their customers. While the actual functionality of an application holds prime importance to the user, the presented interface that a user engages with to achieve these functionalities is equally essential. If the user isn’t able to comprehend how to accomplish the functionality as mentioned earlier, the application, more or less, becomes redundant. This consideration can be augmented by simple facts that no two customers will ever be the same and that none of them will ever share a commonality amongst them as to how they interact, manipulate and communicate with an application. This very fact, however, is often overlooked. This very aspect of un-tailored experiences of almost all commercially available applications can hurt business for the worse. A lot can be done simply by learning from user preferences and applying these learned preferences to predict what a user may or may not like.

AbstractDiesel-powered engines are best suitable for light and heavy-duty vehicles. Because of the high thermal efficiency, it is widely used in the transportation sector. The rapid increase in global fossil fuel demand has raised fuel prices and causes a huge demand for petroleum fuels. And the stringent Emission norms increased the need for a highly efficient engine. In this work, a low heat rejection diesel engine coated with thermal barrier coating is used to test the biodiesel obtained from waste cooking oil. The Thermal barrier coating is given for 30pm, 40 pm, and 60 pm with yttrium stabilized zirconia. It is observed that the thermal barrier coating with 30pm shows better results. The brake thermal efficiency of the engine with LHR and biodiesel observed an increase in its efficiency. And emission concentrations were increasing with respect to waste cooking oil biodiesel when compared with diesel. The experiment was performed in the laboratory with a single-cylinder water-cooled diesel engine. The emission concentrations are measured with a portable emission analyzer.
