4.6. HEAT TRANSFER OUTSIDE VARIOUS GEOMETRIES IN FORCED CONVECTION
4.6A. Introduction
In many cases a fluid is flowing over completely immersed bodies such as spheres, tubes, plates, and so on, and heat transfer is occurring between the fluid and the solid only. Many of these shapes are of practical interest in process engineering. The sphere, cylinder, and flat plate are perhaps of greatest importance, with heat transfer between these surfaces and a moving fluid frequently encountered.
When heat transfer occurs during immersed flow, the flux is dependent on the geometry of the body, the position on the body (front, side, back, etc.), the proximity of other bodies, the flow rate, and the fluid properties. The heat-transfer coefficient varies ...
