Laminar fluid and heat flow through an opened rectangular cooling chamber

Abstract

A numerical model was developed to study the laminar flow and temperature fields in a flow-through rectangular cooling chamber. Hot fluid is introduced into one end of the chamber and withdrawn from the other end. The top of the chamber is exposed to the atmosphere for cooling and the remaining side-walls are all insulated. The Reynolds number Ro considered is in the range of 100 to 1000 and the densimetric Froude number Fo considered is in the range of 0.5 to 50.0. Numerical experiments that the flow fields and temperature profiles in the flow-through cooling chamber are strong functions of both the Fo and the R°. Comparisons were also made with available experimental and prototype data. © 1991.
