Experimental & Numerical Investigation for Heat Transfer and Flows in a $45^0$ Inclined Ribbed Square Channel

$45^0$의 rib이 설치된 채널에서의 열전달과 유동특성의 실험 및 수치해석

Numerical and experimental investigation of incompressible turbulent flow and heat transfer through square channels with varying number of ribbed walls were conducted to determined pressure drop and heat transfer. The CFX solver used for the computation. The rough walls have a $45^0$ inclined square rib. Uniform heat flux is maintained on whole inner heat transfer channel area. The numerical results agreed well with experimental data that obtained for 7600$D_h$) of 0.0667. The results show that values of local heat transfer coefficient and friction factor increase with an increasing number of ribbed walls.
