相变材料热控系统内部接触热阻的辨识方法研究
Study on thermal contact resistance estimation in the phase-change material thermal control device
摘要
Abstract
In this article, the parameter estimation method is used for identify-ing the thermal contact resistance at the interface heiween the container and the phase-change matenal(PCM) in .the thermal control device. The steady and transient thermal contact resistance is obtained by sensitivity method and conjugate gradient method respectively. The results indicate that these methods proposed in this work are characterized with high computing efficiency, and can be used to improve the prediction accuracy of melting rate for PCM thermal control device.关键词
