An attempt to simplify the transient heat transfer simulation of a building facade cavity

Abstract

In the present work, an attempt has been made to validate a simulation procedure for the analysis of transient heat transfer in a building facade cavity. In principle, the convection and radiation heat transfer between the facade cavity and the surroundings are calculated using relevant correlations without modeling the air domain surrounding the building facade. Different turbulence models have been tested and compared with the experimental results. The presented approach gains the importance when it is required to analyze building heat transfer problems using CFD simulation tools like CFX, FLUENT etc as it reduces the computational time.
