Modeling the Heat Exchange in Cavities of Building Constructions Using COMSOL Multiphysics®
Double walls provide stability to the structure and separate the controlled indoor climate from the outdoor fluctuating environment. In this study we want to receive more insight in the heat exchange between the walls through the cavity in between, by computer simulations and verifications. Simulations and calculations with several variants of the cavity wall should give information about the effects of influence factors to the different heat transfer mechanisms: radiation, convection and conduction. The main problem could be the accuracy of the simulated airflow in the cavity and the accompanying heat exchange near the cavity surfaces. In the paper we present a systematic approach and some guidelines for modeling the heat exchange in cavities of building constructions.
