Now, we look at a more complicated heat transfer process, namely the loss of heat from the surface of a PCB to the ambient air. This situation is more challenging to describe mathematically since it involves the simultaneous processes of heat spreading by conduction and heat extraction over the surface of the board by convection and radiation.

The partial differential equation for conductive heat transport with a heat source seems to be not used in books. At least not with what I could find. The only example I found was one given in my course on heat transfer. It was one describing the heat transfer through an insulated electrical wire. The current causes the wire to heat up.

Heat transfer from a horizontal flat surface greatly depends on its position (upwards or downwards) relative to the direction of buoyancy force and also on body dimensions. The greatest coefficient of heat transfer with a free flow near a horizontal plate should be expected at the places of maximum flow rate, i.e., at the plate ends.

For isothermal (constant temperature) incompressible flows energy equation (and therefore temperature) can be dropped and only the mass and linear momentum equations are solved to obtain the velocity and pressure fields.
Heat transfer behaviors are classified into heat conduction, heat convection, and heat radiation. The corresponding governing equations are presented.
