摘要
运用FLUENT数值模拟软件分析了平板集热器(倾角)变化对集热器传热特性的影响,保证其结构参数不变,通过对5组不同倾角(0°、30°、45°、60°、75°)的数值模型进行非稳态模拟,对模拟数据进行分析,得出了平板集热器不同倾角对集热器传热性能变化的影响。
This paper used numerical simulation software FLUENT to analyze the collector heat transfer characteristics and simu-lated the unsteady state by means of a numerical model in five different angles(0°,30°,45°,60°,75°)under the condition of constant structure parameters.By analyzing the data,a conclusion was made on the effects of heat transfer characteristics while the collector located in different angles.
