Analytical solution of the inverse transient heat conduction problem under known temperature variations at two points of the same section of an annular homogeneous simulator

An analytical solution of inverse transient heat conduction problem taking place in treating experimental data on cooling hot annular surfaces (the rewetting phenomenon) is considered. Two temperature-time dependences are supposed to be known at two different points of a section, the temperatures and interval volume heat generation being smoothed by cubic splines. The solution may be used for treatment of experimental data on transient heat transfer in one-dimensional approximation. 4 refs
