Abstract:
The gas and liquid flow field inside a centrifugal nozzle and in an area near the exit of the nozzle was simulated based on a CFD code developed for numerical simulation of the whole flow field of centrifugal nozzle. The geometry of the liquid film formed in the nozzle and its development after the liquid film emanating from the nozzle was predicted. The spray cone angle was directly obtained on the basis of numerical simulation. The gas-liquid interface was captured by using VOF method. The turbulence effect of the gas and liquid flow was simulated with RNG k-ε two-equation model. TVD scheme was incorporated into the VOF method during the solution of the fluid volume-fraction equations. The computational results agree with the experimental measurements. The computational model and the numerical algorithm are validated.
