EFFECTS OF BUOYANT BODY FORCES ON FORCED CONVECTION IN HEATED LAMINARIZING FLOWS
Аннотация
The forced upflow of gases heated in circular tubes is studied by operating in the low Reynolds number range where both laminarizing flows and essentially turbulent flows may occur. Numerical solutions for the property-coupled, internal boundary layer equations governing this continually developing flow-predict that buoyant forces improve heat transfer performance, but experiment demonstrates they can
inhibit heat transfer in turbulent flow.
