Abstract:
The integration of building Energy Simulation (ES) and Computational Fluid Dynamics (CFD) programs eliminates many assumptions employed in the separate simulations, resulting in more accurate predictions of building performance. This paper discusses the methods used to determine convective heat transfer on interior surfaces of building envelope, which links ES with CFD programs. The study found that the size of the first grid near a wall in CFD simulations is crucial for the correct prediction of the convective heat. The study also found that negative convective heat transfer coefficients may cause divergence and instability of the coupled simulation.
