  • Issued also as CD
Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Mechanical Power Engineering Summary: The main objective of the research conducted in the thesis is to study the airflow regimes and thermal comfort in metro cabin using computational fluid dynamics (CFD) software, FLUENT 17.2.The study is carried out through seven modelling configurations of air terminals to find the best location and shape of air terminal. Another study is presented to find the effect of different supply air temperature, and finally study the effect of different ventilation rate. Configuration 7, rectangular inlets at ceiling sides with rectangular outlets at sides under passengers seats, with supply air temperature12oC and ventilation rate 30 L/s per person achieves a good agreement with the ASHRAE comfort conditions within the occupied zones
