by the usage of the heat conduction equation of Fourier-Kirchhoff. To derive this equation it is considered the process of heat flow by conduction from a solid body of any shape and volume V located in an environment of temperature T 0 (t) [1]. Two processes can take place: the generation of heat inside the body and the heat

HEAT CONDUCTION EQUATION H - Wright State University

Heat conduction in a medium, in general, is three-dimensional and time depen-dent, and the temperature in a medium varies with position as well as time, that is, T T(x, y, z, t). Heat conduction in a medium is said to be steady when the temperature does not vary with time, and unsteady or transient when it does.
