DEVELOPMENT OF A NOVEL CFD APPROACH FOR PREDICTING MULTIPHASE FLOW ENHANCED BY MACHINE LEARNING

Accurate estimation of interface orientation is crucial for ensuring both the accuracy and robustness of Volume of Fluid (VOF) schemes in multiphase flow simulations, especially when using non-uniform Cartesian meshes. Conventional gradient reconstruction approaches, such as least-squares (LSQ) methods, often suffer from significant errors and strong oscillations on highly stretched grids. This…
