摘要: A new study area of constructal theory is presented by applying design on multiple heat sources which connected to and cooled in a square-shaped fin. Analyzing the optimal location fin for several configurations primary goal this study. According theory, favorable distribution achieved minimizing global thermal resistance body. Since might be contemplated as heat-generating electronic bodies or hot-water pipes, two boundary conditions uniform flux temperature are considered sources. The minimization cases leads hot spot maximization total removal, respectively. Temperature fields calculated using finite element approach MATLAB PDE Toolbox. optimized numerically ...
