The problem of forced convection in a cavity is very well know and widely studied in the field of fluid mechanics. Numerous numerical techniques are present in literature which successfully simulate the fluid flow in a cavity upto a certain degree of accuracy. This present study is inspired by the physical phenomenon of fire in a ventilated aircraft cabin. Fluid flow inside a cavity is simulated numerically and the boussinesq approximation is considered in all the simulations. The governing equations and boundary conditions are solved using a commercially available code, namely Ansys Fluent. Benchmarking is done by solving the classic problem of a differentially heated two dimensional enclosed cavity. In first part of this study a rectangular cavity with vents is considered. Heat flux is applied to the bottom wall of the cavity. The inlet velocity and the heat flux applied are considered as parameters in the simulation. Different configurations of the cavity are considered by changing the location of the inlet and outlet vents. The simulations run are laminar as well as steady state in nature. The effects of buoyancy for varying heat fluxes are considered in detail. Comparative studies are done to find the best configuration in terms of heat removal. The second part of this study involves the numerical simulation of forced convection in a two dimensional aircraft fuselage cross-section with contains two seats. The seats are modeled as zero thickness walls and a temperature gradient is created by applying heat flux to them. The simulations are transient as well as turbulent in nature. Different configurations of the cross- iii section are considered. The velocity vector fields and the temperature contours are studied in detail. Comparative studies are done to find the most efficient configuration for heat removal.
