Numerical Simulation of Water Jet Flow Using Diffusion Flux Mixture Model

Abstract EN

A multidimensional diffusion flux mixture model was developed to simulate water jet two-phase flows.

Through the modification of the gravity using the gradients of the mixture velocity, the centrifugal force on the water droplets was able to be considered.

The slip velocities between the continuous phase (gas) and the dispersed phase (water droplets) were able to be calculated through multidimensional diffusion flux velocities based on the modified multidimensional drift flux model.

Through the numerical simulations, comparing with the experiments and the simulations of traditional algebraic slip mixture model on the water mist spray, the model was validated.
