Tag Archives | Heat Conduction Equations

Fourier law of heat conduction is essentially valid for heat flow under uni-directional and steady state conditions. However in many practical cases the temperature may be a function of space co-ordinate as well as time. 1. Heat Conduction Equation in Cartesian Co-Ordinates: Consider the flow of heat through an infinitesimal volume element oriented in a three- dimensional co-ordinate system. The [...]
