Measurement and analysis of heat transfer in porous channels using fluent software

This paper presents the results of heat transfer measurement and analysis for two 5*5 cm porous channels. the channels were made of bronze beads with two different mean diameters, dp=0.72 and 1.59 mm. the local wall temperature distribution and heat transfer coefficients were measured for heat flux of 8000 and 16000 watt/m2 with coolant fluid velocity ranging from 0.16 to 5 m/s and inlet fluid pressure of 1~3 atm. the flow of fluid in porous channels is modeled with using Darcy-forcheheimer-brinkman model. by using fluent software, simulation is done that the geometry figure with gambit is generated.
