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
