... the refrigeration capacity of the system. Simulations were conducted to analyze the thermal efficiency and performance of the new system, and compare it with the system of ORC-VCC (with regenerator). The results show that the η th , η sys , and coefficient of performance (COP sys ) of the new system are higher than...

... its energy consumption. Therefore, in order to further improve the thermal efficiency of the heating furnace and reduce the emission of pollutants, this paper combines the actual operation of the SRT-III heating furnace in the chemical plant to establish a fluid domain model. The effects of different...

... and also it acts as an insulator which minimizes the heat losses during the nocturnal period. Energy balance numerical equations were formulated for all layers in the pond and temperature variation was determined mathematically and experimentally. The maximum thermal efficiencies of the top convective...

..., performance improvement of the LPG cook-stoves is essential. In the present work, the thermal efficiency of a traditional cook stove has been studied both experimentally and numerically for LPG fuel. Based on the knowledge from the computational model concerning flow field and species transport parameters...

... of the system thermal efficiency and the length of the cooler were performed. The effects of the inlet and outlet pressure of the expander, the heat transfer coefficient and the logarithmic mean temperature difference (LMTD) on the system thermal efficiency and the length of the cooler were investigated...

... conformance is shown to decrease with the increasing setpoint. However, the decrease is minimal for Models V, W, Y, and Z, which signifies that there is a potential to increase thermal efficiency by increasing the CRAH setpoint without substantial penalty in thermal conformance. Moreover, partial containment...

...) of 4 compared to the smooth plate. It is found that in contrast to the smooth plate, ribs beneath the absorber plate effectively improves thermal and exergetic efficiency. Maximum enhancement of 36% and 17% is obtained in exergetic efficiency (η ex ) and thermal efficiency (η th ), respectively, for e...

...–air mixture, fuel flow rate, thermal load height, and loading vessel size. The maximum thermal efficiency has been found for an equivalence ratio of 1.4 for the LPG–air mixture and at load height of 20 mm. The heat flux distribution at the bottom of the vessel is found to be bimodal with the higher...

.... The airfoils arrangement creates a suitable passage for the airflow over the brake rotor. The design process is classified into three main steps in which the aim is to increase the thermal efficiency of the disk by the means of the different vane’s geometry arrangements. The NACA-0009 profile, due to its...

...Alex Wohlgemuth; Sandip Mazumder; Dale Andreatta In many developing countries, natural gas, wood, or biomass fired cookstoves find prolific usage. Skirts, placed around the cookpot, have been proposed as a means to improve the thermal efficiency. However, use of skirts has shown conflicting results...
