Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Mechanical Power Engineering Summary: The present work is a numerical simulation for smoke control in underground tunnels, simulation cases investigation aims to study the Smoke propagation, Toxic gases, Temperature and Visibility For these purposes, various simulations were performed in Al-Azhar road tunnel having: 2.4 km length; curved cross section with a width of 8 m and height of 6.5 m; two lanes (each of them used only for one traffic direction);. The tunnel investigated was equipped with a longitudinal ventilation system Three different burning vehicles (Single car, Four Cars, and a bus), placed in the center of the driving lane. Peaks of the heat release rate were assumed to be: 5, 20 and 30 MW for the Single car, Four Cars, and a bus, respectively, simulated as a fire with an unsteady heat release rate resulted from burning Heptane as a fuel at jet fan velocity of 22, 26 m/sec. In this investigation, Fire Dynamics Simulator (FDS) software version 5.5.3 is utilized to simulate six case studies in 80 m long, 8 m wide and 6.5 m height domain with a different fire source (single passenger car, four cars and Bus)
