摘要
Abstract
The uniformity and stability of the paraffin temperature distribution in the phase change heat storage box with the addition of foam copper into the pure paraffin were predicted by Fluent software. The simulated results showed that the addition of foam copper greatly improved the heat recovery performance of paraffin and shortened paraffin phase transition time. Moreover, after adding foam copper, the paraffin inside temperature difference decreased significantly, the temperature distribution became more uniform, and top overheating and bottom un-melting caused by nature convection were effectively alleviated. The average error between the simulated results and test data were within 15.7%, which was in good agreement with the measured values.关键词
