Pressure Distribution Sensitivity To Turbulence Models For Cubic Buildings
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 2
Abstract
Numerical methods have been developed in the past decades to study the flow field and pressure distribution around buildings. The Computational Fluid Dynamics (CFD) technique is one of the most efficient methods. The CFD technique includes a wide range of turbulence models suitable for predicting airflow and mean pressure coefficient values. These models include Reynolds-Averaged Navier-Stokes turbulence models (RANS), Detached-Eddy Simulation (DES) model and Large-Eddy Simulation (LES) models. In this paper, a cubic building shape, which include five square faces, was studied to evaluate and validate the numerical results of various CFD turbulence models with available experimental works. The contours of wind pressure coefficients and wind flow around the cube have been determined using these different turbulence models. The results have been compared with experimental and other theoretical results. Further, the values of mean pressure coefficient (Cp) on cubic faces are compared with those values in codes and standard. The results are summarized and discussed.
