Numerical Simulation Study of a New type Solar Collector Wall System

摘要

In this paper, a new kind of solar collector wall system was designed. Numericul simulation for the orifice plate solar collector wall was carried out to analyze the change of the distributions of the temperature and velocity and the heat collecting efficiency under the conditions of different air inlet velocity. The results shows that the temperature stratification decreases with the increase of the inlet velocity, and the velocity field stratification enhances with the increase of the inlet velocity, and the collection efficiency first increases then decreases with the constantly increasing inlet velocity, and the collection efficiency is the highest when the inlet velocity is 2.5 m/s. up to 81.34%.
