VENTURI-FLOW COOLING SYSTEM: COMPARISON OF NUMERICAL AND EXPERIMENTAL RESULTS 942177

A detailed numerical investigation of the conjugate heat transfer problem in an annular-type venturi-flow cooling system, meant for removal of heat from localized, high power heat sources, has been carried out for a wide range of Reynolds numbers. Comparison with experiments show qualitative agreements for all quantities of interest, but there are some quantitative differences. Possible reasons are given. Results for the venturi- and simple pipe- flows are also compared to assess the relative merits of these two systems.
