The Effect of the Ratio of H/W on the Performance of the Hybrid Wall Powered by Solar Energy

Abstract:

The performance of the hybrid wall powered by solar energy was numerically simulated. The factor of H/W was discussed The performance parameters include the induced air mass of the outlet, the induced air velocity of the outlet and the temperature difference between the inlet and the outlet. The results show that ratio of H/W has an important effect on the performance of the hybrid wall powered by solar energy. The induced air mass of the outlet is decreased linearly with the ratio of H/W in a logarithmic coordinate. The temperature difference between the inlet and the outlet increases with the increasing of the ratio of H/W. But for the induced air velocity, it increases with the increasing of the ratio of H/W, and when the ratio is higher than 10, it decreases with the increasing of the ratio of H/W.
