摘要

本文介绍了两种方法来分析带孔吸收体的太阳能集热器中强制对流固定气流的动力学和热行为。这些穿孔是垂直的(板1)和倾斜的(板inc)到保温墙。采用两片吸收板，考察了吸收板孔隙率和注入空气流量对集热器热效率的影响。对两种吸收板的轴向、径向速度分布、速度场、温度分布进行了对比研究。

Numerical study on effect of mass flow rate and porosity on the thermal performance in the solar sensor with porous absorber

Two techniques are described in this paper to analyze the dynamic and thermal behavior of a stationary air flow of forced convection in a solar collector with a perforated absorber. These perforations are vertical (plate 1) and inclined (plate inc) to the wall of insulation. Two absorber plates were used to determine the effect of absorber plate porosity as well as injection air flow rate on the collector thermal efficiency. The profiles of axial and radial velocity, velocity fields, temperature then a comparative study of the two absorber plates have been investigated.
