Abstract: A confined turbulent jet diffusion flame is studied using the probability density function(PDF) approach together with the k-ε two-equation model. The effect of solid wall and pressure gradient on the velocity and scalar is mainly concerned with. Then two confined turbulent combustion fields with different dimensions are simulated, of which the fluid structure, flame structure and flame shape are studied. In the end, the result is analyzed and conclusions are made.
