Abstract:
Effective cooling of electronic components arranged in vertically oriented parallel boards is considered. The objective of the present investigation is to examine the effects of global flow in a channel upon the local heat transfer from a flush mounted source. The concept of adiabatic heat transfer coefficient and its application is clarified by reviewing its origins and examining a series of numerical experiments on a well-defined model problem. Simulations are conducted in the regions of laminar forced flow, mixed forced and local buoyant convection and buoyancy-induced flow. Local buoyancy effects cause a departure of adiabatic heat transfer coefficient from its value for pure forced convection. Calculations cover the range 10-3 at Pr = 0.7. The superposition principle for temperature fields is validated for forced convection. The effects of mixed convection upon this phenomenon is subsequently examined.
