Numerical prediction of small scale cavities using a coupled mixture-bubble model
Övrigt konferensbidrag, 2019

In this study a hybrid Eulerian mixture - Lagrangian bubble model is developed for numerical simulation of cavitating flows. In this model, the large scale cavities are represented in the Eulerian framework using the homogeneous mixture model, while the small sub-grid structures are tracked as Lagrangian bubbles. Also, at each time step small cavity structures in the Eulerian framework are transformed to the Lagrangian framework to be treated as sub-grid bubbles and vice versa. Using this model, it is possible to represent various cavity structures of different length scales with reasonable computational cost.
