摘要

设计了一种新型立式集热板太阳能热气流电站系统

通过建立数学模型

利用CFD数值模拟软件Fluent对该电站系统太阳能烟囱内的速度场、压力场进行数值模拟

研究了烟囱高度和太阳辐射强度的变化对烟囱内空气速度场和压力场分布的影响。研究表明

烟囱高度和太阳辐射强度的增加可以强化烟囱的抽吸作用

有利于提高太阳能热气流发电输出功率。

Abstract

A new type of solar energy power station system with vertical heat-collecting plates and using hot gas flow has been designed.Through establishment of the mathematic model and adopting the CFD numerical simulation software Fluent

the numerical simulation of velocity field and pressure field in solar energy chimney of said power station system has been carried out

the influence of chimney height and radiation intensity variation of the sun upon velocity field and pressure field of air in the said chimney being studied.Study shows that the increase of chimney height and radiation intensity of the sun can strengthen the sucking effect of said chimney

it is advantageous to increase the output power of said solar energy power station.
