Numerical investigation of heat transfer in a sintered porous fin in a channel flow with the aim of material determination

摘要: Extended surfaces are one of the most important approaches to increase heat transfer rate. According Fourier law, increases by increasing contact surface body and fluid. In this study, effect has been investigated on two sets engineered porous fins, in which balls with different materials sintered together. The fluid flow through channel is considered incompressible, steady three-dimensional. fins made copper, aluminum steel 0.6 1.7 mm diameters single-row, two-row modes studied, pressure drop these checked. Also, volume analysis rigid also provided. addition, diameter material temperature distribution coefficient examined cases constant flux at base. results show that fin a behavior compared other fins; suitable for copper aluminum, respectively. it found utilization type connection decrease about 39% 37%.
