SPH tensile instability in the formation of viscous liquid drops

Abstract Submission Deadline : November 30, 2023

Manuscript Submission Deadline : December 25, 2023

Special Issue Description

The tensile instability may result in an unphysical clustering of particles in simulations of elastic solids and viscous fluids using smoothed particle hydrodynamics (SPH). Recent research has demonstrated that artificial stress whose form is determined from a linear perturbation analysis of the entire set of governing SPH equations can be used to alleviate the instability in simulations of elastic or brittle substances. We demonstrate that the same construction that works for elastic materials may also work for viscous fluids under the condition that the constant parameter entering the formulation of the artificial stress is suitably chosen. A linear analysis cannot be utilized to determine the relevant form of artificial stress for a viscous fluid. We use the production of a circular van der Waals liquid drop as a good test case and demonstrate how adding fake viscous force and energy generation terms to the traditional SPH equations of motion and energy, respectively, removes the tensile instability.
