Heat equation

Describes how temperature spreads through a region over time by conduction. It is used to model heat flow and, in general form, any diffusion process.

\frac{\partial u}{\partial t} = \alpha \nabla^2 u

What the symbols mean

temperature field u(x,t) (K)
time (s)
thermal diffusivity (m^2/s)
Laplace operator with respect to spatial coordinates
