  Our discussions thus far have been limited to the case that the temperature is not a function of time. For many applications, it is necessary to consider the variation of temperature with time. In this case, the energy equation for classical heat conduction, eq. <math>\rho {c_p}\frac{{\partial T}}{{\partial t}} = \nabla \cdot (k\nabla T) + q''' </math> from [[Basics of heat conduction]], should be solved. If the thermal conductivity is independent from the temperature, the energy equation is reduced to eq. <math>\frac{1}{\alpha }\frac{{\partial T}}{{\partial t}} = {\nabla ^2}T + \frac{{q'''}}{k}</math> from [[Basics of heat conduction]]. Analysis of transient heat conduction using lumped (zerodimensional), onedimensional, and multidimensional models will be presented in this section.
