What's the name of the heat transfer equation?

It looks like the Fourier/Laplace equations for thermal conductivity, but has some extra's. Attached is a screenshot of the full equation.

Hi

I'm not sure I catch fully your question, for me the equation is the full thermal PDE wit to the left, the time dependency term, the displacement/convective term and to the right the conduction term and the different body and boundary heat fluxes

Good luck

COMSOL also calls it the convection-diffusion equation. Check documentation for “Coefficient form PDE” for more details. If you remove the transient and the convective terms (on the left) you are left with the Poisson equation.
