Feasibility of numerical simulation of flow through COIL 3-D nozzle with VICON code

VICON code was used to simulate COIL cold flowfields, and the obtained geometry nicely reflected the geometry change of the simulated equipment. The grid dimensions of primary and secondary flow reflected gas characteristics of the two dimension plane. The simulation results of different flux showed that excess or insufficient penetration led bad mixing. Changing process of horseshoe that secondary flow came out from orifice and entered primary flow was showed by simulation of chemical reaction. Those show that the VICON code may be used to study flowfield properties on COIL nozzle.
