This paper proposes and validates two new particle regularization techniques for the Smoothed Particle Hydrodynamics (SPH) numerical method to improve its stability and accuracy for free surface flow simulations. We introduce a general form of the Dy

This paper develops a consistent particle method for capturing the highly non-linear behavior of violent free-surface flows, based on an Enhanced Weakly Compressible Moving Particle Semi-implicit (EWC-MPS) method. It pays special attention to the eva

In this work, we develop an enhanced particle shifting strategy in the framework of weakly compressible &delta
+-SPH method. This technique can be considered as an extension of the so-called improved particle shifting technology (IPST) proposed

We develop and validate a three-dimensional particle method based on an Enhanced Weakly-Compressible MPS approach for modeling immersed dense granular flows. For this purpose, we adopt a generalized rheological model, using a regularized visco-inerti

Similar to other particle methods, the Weakly-Compressible MPS (WC-MPS) is known to suffer from numerical instabilities and unphysical pressure fluctuations. Here we develop, adapt and evaluate a series of enhancement techniques to improve the stabil

In this study, different methods of long-term morphological modeling are briefly reviewed. These methods include input reduction, schematization of flow perturbation induced by bed changes and increase of the morphological time step. In the discussio
