摘要

集热器形状及烟囱偏离中心对建筑型太阳能烟囱发电厂（BISC）的性能有较大影响。采用realizable k-ε模型和DO辐射模型对典型太阳能烟囱（SC）结构进行三维流动与热辐射的耦合求解

并通过对比实验数据与文献模拟结果

验证了数值模型的准确性。采用相同的数值模拟方法对22组不同集热器形状和烟囱位置的SC模型进行计算。结果表明

对于圆形集热器

SC的输出功率受集热器位置偏移量Δd影响

随着Δd增大

输出功率下降幅度逐渐增大;当Δd取最大值时

输出功率相较于Δd=0时降低56.8%。对于方形集热器

SC的输出功率变化受Δd影响的规律与圆形集热器相似

但下降幅度相对较小;当Δd取最大值时

输出功率相较于Δd=0时降低52.0%。此外

方形集热器SC的输出功率还受角度偏移量Δθ影响。当Δθ为45°时

随着Δd从0增大0.8

输出功率降低43.9%

表明Δθ增大会减弱Δd增大带来的负面影响。

Abstract

The thermo-fluidic performance of Building-Integrated Solar Chimneys （BISC） is influenced by solar collector geometry and chimney off-center configuration. The present investigation employs three-dimensional numerical modelling integrating the realizable turbulence model with the DO radiation modelling to resolve coupled heat transfer and airflow dynamics in solar chimney （SC） systems

and the accuracy of the numerical model is confirmed by comparing the experimental data with the simulation results from the literature. Applying this validated methodology

a systematic parametric study is conducted on 22 geometrically distinct SC configurations. The results show that for circular collectors

the output power demonstrates significant sensitivity to deviation factor

and the decrease of the output power gradually increases with the increase of

with a maximum reduction of 56.9%. For square collector

the variation of the output power of the SC is affected by in a similar pattern to that of the circular collector

albeit to a lesser extent （52.0%）. In addition

the output power of the SC for the square collector is also affected by the angle factor . When is 45°

the output power of SC decreases by a maximum of 43.9% as increases

and an increase in attenuates the negative effect of an increase in .
