Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Mechanical Power Engineering Summary: The present thesis is devoted to numerical investigation that change in the angles of air throwing, air change per hour (ACH), also numbers, positions and dimensions of air extract grilles are studied to revealed the impact on the overall comfort levels for people. The study is carried out using (CFD) simulation techniques as entrenched in the commercially available CFD code (FLUENT 19). 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 {u2013} f model equations for turbulence closure. The results had shown the best configuration among the other configurations when eleven supply grilles distributed uniformly on ceiling with angle of throwing air is (15{u00BA}) with horizontal, and four extract grilles distributed uniformly on the edges of the ceiling, at ACH=6
