Transient Heat Conduction
In transient heat conduction, the thermal boundary conditions are time dependent. The mathematical model for a transient heat conduction problem includes the temperature distribution within the body and the thermal boundary conditions at the surface of the body.
3.2 LUMPED PARAMETER ANALYSIS (INFINITE THERMAL CONDUCTIVITY)
If a body at uniform temperature is suddenly exposed to a different temperature, then the temperature change in the interior of the body depends on the resistance to heat transfer internally and at its surface. If the resistance at the surface is much greater than at internal, then the internal body temperature will be almost uniform. In transient heat conduction problems, this situation ...
