TURBULENT FLUID FLOWS AND HEAT TRANSFER CHARACTERISTICS IN FLOW CHANNELS WITH DISTRIBUTED CHIP MODULES

A study is carried out to investigate the characteristics of turbulent fluid flow and heat transfer in the entrance region of a flow channel containing heat-generating modules of different sizes and distributions. The flow is described by Reynolds averaged Navier–Stokes equations and k-e model with wall function treatment. The prediction for flow and heat transfer characteristics has been made and compared with published experimental results. The computational results showed good agreement for performance parameters such as Nusselt numbers and Coefficient of pressure with experiments. The investigation is performed for Reynolds number values of 5000 and 15,000, and for two different geometrical configurations. Flow and heat transfer characteristics with varying parameters are also discussed.
