Periodically generated Vortex Rings Equations: 3D, unsteady , incompressible Navier-Stokes equations using curvilinear immersed boundary method Implicit Momentum Solver: Newton-Krylov method with approximate analytical Diagonal Jacobian

Periodically generated Vortex Rings • Equations: 3D, unsteady , incompressible Navier-Stokes equations using curvilinear immersed boundary method • Implicit Momentum Solver: Newton-Krylov method with approximate analytical Diagonal Jacobian • Poisson solver: FGMRES with Multigrid preconditioner • Computational Grid Size : Around 22 million grid points (225*225*433) • Required Computational Resources: Approximately 160 cores for 100 hours to reach quasi-steady state depending on different test cases Iman Borazjani Scientific computing and biofluidics lab 1
