Incompressible SPH method based on Rankine source solution for violent water wave simulation
TL;DR: Numerical results clearly show that the newly developed ISPH method does need less number of particles and so less computational costs to achieve the similar level of accuracy, or to produce more accurate results compared with the traditional SPH and existing ISPH when it is applied to modelling water waves.

Explicit incompressible SPH algorithm for free-surface flow modelling: A comparison with weakly compressible schemes
TL;DR: In this paper, the authors compared three numerical schemes for incompressible fluid flow with Smoothed Particles Hydrodynamics (SPH) and showed that EISPH led to results overall similar to WCSPH and δ-SPH but with smoother pressure dynamics and faster computational times.
