摘要
建立了平板微热管阵列式太阳能空气集热器的三维稳态模型,运用Gambit及Fluent软件对单个集热单元的物理模型进行了网格划分和数值计算,对单管的换热及流动情况进行了模拟研究,并通过实验进行了验证。结果表明,模拟结果与实验结果吻合较好,偏差在12%以内,说明了模型建立的合理性。该研究为今后平板微热管阵列太阳能空气集热器的进一步设计和优化提供了理论依据。
We constructed a 3-D steady-status model for flat micro-heat pipe arrays solar energy air collector. We also performed grid segmentation and numerical calculation for the physical model of single heat collection unit with software Gambit and Fluent. We further simulated heat exchange and flow of single pipe and verified its effectiveness by experiments. Experimental results show that the simulated results fit well with the experimental results, less than 12% deviation. This demonstrates the rationality of the model. Our research can provide theoretical basis for optimization design of flat micro-heat pipe arrays solar energy air collector in future.
