This paper investigates the impact of spatial composition on the effectiveness of passive cooling by natural ventilation in a comparative study of the conical roofed Harran houses in Turkey and a passive solar home in the Midwest of the United States. While the projects are distinct and are situated in two extreme climate zones (hot and arid and continental humid) both projects have in common open variable configurations of multiple interconnected spaces. Computational fluid dynamics (CFD) simulations using OpenFoam were used to investigate the fundamental airflow characteristics and the resulting interior temperature and velocity profiles. The simulations were initialized as ...

Fast Cfd Simulation Method For Indoor Environment Modeling, Haidong Wang

Civil Engineering Graduate Theses & Dissertations

Computational Fluid Dynamics (CFD) has been becoming an important tool in building environment and airflow modeling. Well validated CFD model can provide more detailed and informative results than other computer models and physical experiment. However, the significant computational cost of CFD has always been the main factor that restricting its broader application.

This study reviews the various means of reducing the computational cost of CFD in literature. With considering the characteristics and result accuracy requirement in indoor environment quality (IEQ) study, the most important factors that affect the computing cost are identified: grid resolution, turbulence modeling and velocity-pressure decoupling algorithm ...
