摘要

通过构建负载条件下联合海水淡化太阳能烟囱发电系统(CSPD)的传热传质与流动模型

对单轴轴流式涡轮机进行了模拟研究

并对系统的流场特性及其性能参数进行了计算分析。结果表明:稳态系统热气流能接近90kW时

涡轮机最大轴功率达到34kW

系统流量接近900kg/s时

可以得到较高小时产水量

附加淡水价值后的系统太阳能利用率达到20.53%;合理的调整涡轮机转速可以提高整体系统的性能

有利于CSPD的并网研究及性能控制。

Abstract

The heat transfer

mass transfer and flow model of solar chimney power generation system(CSPD)was established

and the single-axial-flow turbine was simulated

the flow characteristics and performance parameters of the system were calculated and analyzed.The results show that

when the steady hot air energy system was getting closer to 90 kW

the maximum shaft power of the turbine reached34 kW

and it got higher hour water production when the system flow was close to 900kg/s

the solar energy utilization of the system added fresh water value reached 20.53%

thus the reasonable adjustments to the turbine's speed were proved to be useful to improve overall system performance

which is conductive to the electricity grid research and performance control of the CSPD.
