Abstract

A comparison between computational and experimental results for a research combustor R.M. Morris, J.A. Visser and P.J. Venter Department of Mechanical and Aeronautical Engineering, University of Pretoria, South Africa Abstract A detailed experimental and numerical investigation of a single can combustor has been carried out. Using thermocouples, inner and exit gas temperatures as well as temperatures along the liner wall were recorded. These temperatures are then compared to temperatures obtained using a numerical model for the same combustor. The numerical model constitutes a CFD model developed using a commercial CFD code and implementing the presumed-PDF model of unpremixed turbulent reaction. The flow rate at each air jet is the actual flow rate measured at that hole, while the angle at which the air enters is calculated using an empirical formulation of the discharge coefficient. Despite the assumptions made during development of the model, trends and distribu
