Description

CFD code is used routinely to predict air movement and temperature distributions in indoor environment. Especially commercial CFD software is applied against complex geometry and multi-physics phenomenon. In this paper, we discuss the aspects related to numerical errors on choice of turbulence modeling and computational grid concerning the application of commercial CFD code. This paper consists of three examinations, comparison of (1) five different mesh designs, (2) different turbulence model, (3) different commercial CFD code. Finally, recommendations are given for execution of suitable CFD calculations.
