Analysis of CFD for Design Method of Swirl Atomizer
The UFD method was used to analyze the flow field in the swirl atomizer whose geometric structure had been designed with ideal theory algorithm. RNG (Renormalization Group) k-turbulent model was applied to the numerical simulation of the flow field, and SIMPLE algorithm was used to solve the finite difference equations. Through the analysis of pressure and velocity fields get by the numerical simulation, we found that the use of CFD method in the swirl atomizer design is beneficial for getting more detailed and accurate flow structure and advantageous to analyze the influence of different nozzle geometry, and then given a reasonable design opinion.
