摘要
本文建立了分析带有相变微胶囊的潜热型热功能流体的流动和换热过程数理模型,应用有限差分法和移动热源法进行联合求解。计算结果表明,相变微胶囊的加入:较好地提高了流体的换热性能。获得了相变颗粒大小和体积分数对强化换热影响等结果。计算结果对该类流体的设计和应用提供了理论依据。
A physical model has been developed to analyze the enhanced heat transfer process of the latent functionally thermal fluid with microencapsulated phase change material. The problem is solved by the combination of the finite difference method and the moving heat source method. The calculated results reveal that putting the phase change microcapsules into the fluids better improve the heat transfer capabilities of the mixture. By the calculations, the effects of capsule radius and concentration of particles are obtained. The numerical results provide the theoretic basis for the application and design of the latent functionally thermal fluid.
