翅片管外相变材料熔化过程的数值模拟
Numerical simulation of melting process for phase change material outside heating tube with fins
摘要
Abstract
The low thermal conductivity of phase change material (PCM)is the main resistance for heat transfer in latent storage system.The main way to increase the heat storage efficiency is to use finned tube.The numerical simulation of melting process for phase change material outside heating tube with fins was conducted to obtain the change rule of the solid-liquid interface with time.The effects of tube fin parameters of fin thickness and gap on melting time were analyzed.The results show that the overall thermal performance is markedly increased by decreasing the gap of fins,while increasing the fin thickness and conductivity has slight improvement.关键词
