WebJul 25, 2007 · A generalized thermal boundary condition is derived for a material region, representing all thermal effects of an adjacent thin layer. The boundary condition is obtained by considering the equations of heat conduction in each region and performing an asymptotic expansion of the temperatures about the ratio of thermal conductivities. From … Web13-13C The region of flow over which the thermal boundary layer develops and reaches the tube center is called the thermal entry region, and the length of this region is called the thermal entry length.
