Numerical analysis of high-load burner flow

摘要

The high-load burner is analyzed by employing the computational fluid dynamics(CFD) code PHOENICS. The SIMPLEST algorithm and the Jones-Launder e-a two-equation turbulence model are used to simulate the three dimensional burner flow field. The calculated results show that the velocity profile of main flame orifice is strongly affected by the diameter of nozzle and the position of nozzle. The velocity profile of diverging-tube centerline is strongly affected by the size of nozzle diameter.
