Analysis of the Thermal Performance of External Insulation in Prefabricated Buildings Using Computational Fluid Dynamics

This paper investigates the thermal performance of prefabricated exterior walls using Computational Fluid Dynamics method to reduce energy consumption. The wall was numerically simulated software ANSYS Fluent. composite containing cavity is taken as research object in this after analysis. simulation suggests that when thickness 20 mm and 30 mm, heat transfer coefficient air-sandwich 1.3 1.29, respectively. Therefore, optimal width most suitable material aerated concrete block. In addition, a comparative analysis conducted on temperature under different conditions. It proven an intelligent environment control system can significantly improve efficiency provide solid theoretical basis for further external insulation buildings.
