We have employed the large eddy simulation (LES) approach to investigate cavitation noise characteristics of an unsteady cavitating flow around a NACA66 (National Advisory Committee for Aeronautics) hydrofoil by employing Eulerian-Lagrangian based multiscale model. A volume fluid (VOF) method simulates cavity, whereas Lagrangian discrete bubble model (DBM) tracks small bubbles. Meanwhile, is determined using Ffowcs Williams-Hawkings equation (FW-H). analysis has shown that, in comparison...
Numerical simulations of multiphase flows with both interfaces and discrete particles are challenging because they possess a wide range length time scales. Meanwhile, the volume fluid (VOF) method is suitable for resolving interface, while particle model (DPM) under Lagrangian frame better simulates unresolvable particles; multiscale VOF–DPM combined urgently needed flows. The present work implements solver that includes two-way transition algorithm to transformation between continuous...
The slag droplet entrainment is a common phenomenon in steel refining processes, which may lead to inclusions and defects. In the multiphase flow system, distinct interface tiny blobs possess wide range of spatial temporal scales make it hard be simulated. numerical methods, volume fluid (VOF) approach appropriate for capturing interface, but unresolvable blobs, Lagrangian particle tracking (LPT) preferable. This work newly implements bidirectional VOF-LPT transformation algorithm developing...
