My code does not do its job, and I believe that there is something wrong with how I calculate my Fluxes through the four sides of my rectangular cell. Simulation: Thermal Analysis. Though MATLAB is primarily a numerics package, it can certainly solve straightforward diﬀerential equations symbolically. Inhomogeneous Heat Equation on Square Domain. i am new in matlab, i don't know how to do surface plotting. Radiation heat transfer can be described by reference to the 'black body'. The project is to review the FVM formulation for a convective heat transfer problem of compressible air flow in a kind of solar air heater.
