Abstract

Using an existing control volume based computer code, swirling flow field and combustion of fuel and air are computed. In order to model turbulent stresses, a modified Bossinisque scheme in swirling flows is used. Turbulent flow is modeled using a RNG k-ε model and combustion is modeled by two well-known models, i.e., the bi-molecular Arrhenius relation and the EBU (Eddy Break Up) model. The results of the numerical solution of a combustion chamber are compared with the existing experimental data for velocity and temperature distributions. The comparison shows satisfactory agreement between numerical and experimental results. The lower reaction rate computed using the above models is used in the computation. In this study, variable fluid properties have been used and their effects are presented. It is shown that the existence of either swirl or combustion shortens the length of the recirculating region and the same effect is produced by using RNG k-€ instead of the standard turbulence model.
