Smoothed Particle Hydrodynamics simulations of viscoelastic Kelvin-Helmholtz instability —Jack King & Steven Lind, University of Manchester

<p>Kelvin-Helmholtz instability of a Giesekus jet in contraflow with a (nearly) Newtonian fluid in a doubly-periodic domain. Colour indicates internal (molecular) deformation. Simulations used an in-house multiphase incompressible Smoothed Particle Hydrodynamics code, with 115200 particles. Increasing elasticity causes higher growth rate, finer filaments and increased transverse mixing.</p>
