Abstract
The present thesis is devoted to numerical investigation of the change in location supply-extract air are studied to revealed the impact of changing the location on the overall comfort levels and indoor air quality for people. The study is carried out using computational fluid dynamics (CFD) simulation techniques as embedded in the commercially available CFD code (FLUENT 15). The CFD modelling techniques solved the continuity, momentum and energy conservation equations in addition to comfort parameters PMV and PPD based on fanger{u2019}s model and RNG k-f model equations for turbulence closure. The results showed that the best case among the others cases when the supply and extract air from ceiling
