Nonsteady-State Heat Conduction in a Cylinder
Nonsteady-state heat conduction in a cylinder obeys the following PDE:[more]
where is the thermal diffusivity coefficient expressed in , is the temperature in , and is the radial position in meters.
The initial condition and boundary conditions are
(the temperature at the cylinder surface is kept constant);
This Demonstration shows the temperature profile inside the cylinder at different instants for values of the thermal diffusivity coefficient specified by the user.[less]
