Abstract

The study of how thickness of wall affects the flow rate throughout the building when using the Computational Fluid Dynamics (CFD). By comparing the result to the experimental result would make sure the CFD simulation is in correct matter. Three thickness of the wall has been chosen from the actual size of the wall and simulate under CFD by using different turbulence models. The result for the full flow field is recorded and compared with another simulation method which is the domain decomposition method. The domain decomposition method is simulating without the computational domain. This method greatly reduced the time taken for the simulation which gives the result of the internal flow at the inner building only. From the result taken, the thickness of the wall does not affect the flow rate throughout the building and the velocity ratio throughout the building also constant from the inlet to the outlet of the building. Both methods able to get the velocity ratio which is near to the experimental and both methods give the same volume flow rate which the difference is approximately 4% only.
