Heat Transfer in Fluid Flow
Heat Transfer in Fluid Flow
This Demonstration illustrates the basics of heat transfer in the internal flow of a fluid. The radial temperature profile, mean temperature, surface temperature, and Nusselt number behavior are displayed for a thin-walled pipe with a selection of two different surface conditions: constant temperature or constant heat flux. You can vary the area ratio (surface area over cross sectional area), the Reynolds number, and the Prandtl number in order to observe the effects on the system. In addition, the dimensionless axial position slider lets you see the development of the thermal boundary layer profile along the length of the pipe.
