Abstract: The improvement of device performance of a recycling solar air heater featuring a wire mesh packing was investigated experimentally and theoretically. The application of the wire mesh packing and recycle-effect concept to the present study were proposed aiming to strengthen the convective heat-transfer coefficient due to increased turbulence. Comparisons were made among different desi...

A large share of Ethiopia’s milk production comes from its rural areas. However, this does not undergo further processing into dairy products on a scale due to lack conventional energy sources such as electricity and gas. Hence, the country is utilizing resources maximum possible. In study, possible use solar for pasteurization process investigated by using flat plate collector (FPSC) with with...

The BIS test procedure for performance of solar flat plate collectors allows a certain limit of deviation for the control parameters to define the steady state condition. During actual performance studies, sometimes these limits are exceeded. In this paper an attempt has been made to find out the effect on the performance curve of the collector as a result of exceeding this prescribed limit by ...

Flat plate solar collector (FPSC) is commonly used due to its low price, less complexity, and easier installation operation. The thermal efficiency the main disadvantage of this type collectors. In present study, performance FPSC using alumina oxide -water copper nanofluids are evaluated. effect nanoparticle volume fraction investigated theoretically validated experimentally. A computational fl...

The article is devoted to the determination of thermal stresses in a flat plate solar collector and calculation its optimal size. solution found when moving an elliptical coordinate system. obtained result useful because by varying geometric shape cross-section, it possible reduce level that occur, and, consequently, increase reliability durability design.
