Abstract: natural draft counter flow cooling tower heat and mass transfer numerical simulation has been widely used to optimize the cooling tower design and to improve the thermal efficiency, but in published papers, a few important problems is not attracted attention, such as how does impact grid density to the calculation results; how does impact change of atmospheric density to the calculation results; drop diameter is an important parameter in numerical simulation, but it is not a exact experimental data, it is important to discuss how does impact drop size to the calculation results. This paper will explore and analyze these issues in the numerical simulation.

Abstract: The solar thermal collector performance evaluation system is designed for the actual needs of tests for industrial production and scientific research, which is adequate for stable efficiency, time constant, incident angle modifier and pressure drop measurement on either end of the thermal collector.
