Mathematical modelling and experimental verification of flow field up and down-stream of a V-shaped flame stabilizer

In this paper, the omega-psi method is used to obtain the numerical prediction of whole turbulent compressible flow field containing a complete recirculation zone, and the feasibility of the numerical simulation is verified by visual experimental method. A hybrid mesh system is used in the computation because the flow patterns up and down-stream of the stabilizer are obviously different. A K-epsilon turbulence model is used to calculate mu(T), and the boundary condition of the vorticity on the tip of the stabilizer is treated as discontinuous value.
