太阳能热风发电站集热棚的实验和CFD计算模拟研究

Experimental and CFD computing simulation of solar thermal wind and chimney power system

根据太阳能热风发电原理和工作特点,建立了小型太阳能热风发电集热器实验装置,研究蓄热介质沙子的储热换热能力,通过实验和计算得出:内蒙古地区沙子最高温度出现在16时,温升可达40 K;本文还拟合出一条地表太阳辐射热流曲线,用于后期太阳能热风发电系统计算和工程设计,为内蒙古乌海金沙沙漠太阳能热风发电站的建设提供理论依据.

A small-scale experimental solar collector was established to study the heat storage and heat transfer capacity according to the theory and work characteristics of solar thermal wind and chimney power system. Through experiment and calculation,the results are as follows ：the maximum temperature of the sand in Inner Mongolia is at 16：00 pm and temperature rise can be up to 40 K;a fitting curve of surface solar radiation flux was obtained to calculate and design the solar thermal wind and chimney system later. The theoretical basis was provided for constructing the solar thermal wind and chinmey power system in Wuhai desert of Inner Mongolia.
