数値熱流体解析ソフトの感度解析を使用した同定問題

（素子搭載ベース板間TIMの熱伝導率測定への応用）

抄録

We investigated prediction accuracy of an identification method using sensitivity analysis of CFD software developed by us named as “FlowDesigner”. We applied the identification method to predict the thermal conductivity of TIM with 0.1mm thickness set in between upper and lower base plates by using the measured temperature of targets located in the center of both upper and lower base plates. We clarified that the thermal conductivity of TIM was able to be predicted as 0.2W/m·K within prediction error band of ±10% under the condition of targets temperature measurement error was in between -1 and +0.8 K and heat flow ratio of in-plain direction against thickness direction was in between -1 and +0.8.
