Authors: Cheng Tiancai , Jiang Minzheng
Published: April 2020

To address the common issues of low-production oil wells like unbalanced supply and output, low pump efficiency and system efficiency and high energy consumption, a small-displacement oil pump has been developed. The pump has an enhanced structural strength with solid plunger and the mobility of the pumping oil with offset outlet valve. The outlet valve is located at the highest point of pump chamber when the plunger is at the bottom dead center, which is preferable for the discharge of gas and high gas-liquid and pump efficiency improvement. Combined with the distribution law of oil and gas in vertical pipe flow, it is assumed that the dissolved gas is linearly distributed from the oil inlet valve to the bottom end of the plunger after the pump is introduced. According to the position of the oil pumping valve of the oil pump, the efficiency calculation formula is derived. Then through reasonable matching of working conditions, the influence of various factors on pump efficiency is analyzed. The pump’s pump efficiency is about 10% higher than the API minimum pump diameter (32 mm), which is important for energy saving in oil fields.

Published: April 2020

With the outbreak of oil crisis, heat exchangers as the energy-saving devices have gained more and more attentions. The heat transfer enhancement techniques have been developed to the third generation. Corrugated low finned tube is a kind of helically corrugated tube with trapezoidal shape groove. In this paper, the performance of convective heat transfer inside corrugated low finned tubes was studied experimentally. The results showed that the heat transfer performance could be intensified compared with the smooth tube. The reason was that helical rib generated the secondary flow and longitudinal vortex, reducing the synergy angle between velocity vector and temperature gradient. Moreover, the effects of tube structural parameter and fluid Reynolds number were analyzed. Finally, all the experimental data were fitted as the function of Reynolds number, Prandtl number, tube pitch and rib height. The research results can provide a foundation for designing heat exchangers using this enhancement technique.

Published: April 2020

Estimating net ecosystem carbon exchange (NEE) on regional and global scales is important for the carbon cycle and the greenhouse effect. The eddy covariance technique provides long-term continuous monitoring of site-specific NEE at the tower footprint scale. Remote sensing technology can continuously and systematically monitor multiple information of terrestrial ecosystem at regional scale, and it becomes an important tool to extend NEE to large scale combining with flux data. In present study, according to TG model, we established several new NEE models (using linear regress method based on single variable or multiple variables) that are suitable for Dayekou Guantan forest station with Moderate-resolution Imaging Sepctroradiometer (MODIS) products. Variables include enhanced vegetation index (EVI), land surface water index (LSWI) and land surface temperature (LST, including daytime LST and nighttime LST´). Compared with models based on single variable, models based on EVI, LSWI and LST have the best effect. Results showed that this method had good precision (2008) (R2and RMSE reached 0.8014 and 0.7364, respectively) and generally captured the expected seasonal patterns of NEE. We validated the model using independent flux (2009), which demonstrated this method performed well for estimating NEE (R2and RMSE reached 0.8618 and 0.5538, respectively). In addition, during the whole process, variables had obvious seasonal dynamical characteristics and closely related to NEE seasonal dynamics. However, uncertainty still existed in this method. In future research, more influencing factors should be selected to simulate NEE more accurately and extend the scope of research to a larger extent.
A Coordination Strategy between PV Generators and Storages based on Droop Control in AC Microgrids
Authors: Wang Liang , Wei Wei , Xia Yanghong
Published: April 2020

In an islanded AC microgrid, the coordination strategy between generations and storages is often designed to ensure the stability and economy of the system. In this article, for an AC microgrid dominated by photovoltaic (PV) generators, a strategy based on droop control is proposed to realize the generation-storage coordination. PV generators change their active and reactive power output by catching the changes in bus frequency and voltage, which can prevent storages from over-charged and make the bus voltage more stable. Storages are controlled by a droop algorithm based on state-of-charges (SOCs) to achieve SOCs balance among multiple storages. When the SOCs are too low, secondary loads (SLs) will be removed through a loads management, and the rest primary loads (PLs) will be powered entirely by PVs, which can prevent storages from over-discharged. Simulation based on Matlab successfully verifies the proposed coordination strategy.
