管肉厚を考慮した千鳥配列管群の伝熱解析

The microtube heat exchanger performs heat exchange by setting up alley tube group in a duct. In the conventional analysis, since the wall thickness of the pipe is thin, the analysis was performed by applying isothermal conditions to the side of the pipe. However, in recent years, as the processing technology is digitized, the increase in the wall thickness with respect to the pipe diameter becomes remarkable. Therefore, in this analysis, numerical analysis of the flow channel with tubes with different wall thicknesses was conducted, and the flow characteristics of the fluid and the heat transfer characteristics inside the tube were investigated.
