Spline Volume Tracking for Interfacial Flowsavier-Stokes equations on unstructured grids, using staggered finite volumes. A cubic spline interface interpolant which preserves the volume fraction distribution is introduced. Interface adaptive and/or interface aligned deformable grids are reconstructed at each time step with help of either a li

Modeling of Free Surfaces in Casting Processesinterface during solidification and the moving liquid-gas interface during mold filling. Thus, the simulation of fluid flow with free surfaces is a key part of a tool simulating casting processes..Three approaches modeling fluid flow applied to casting are presented. There are a Finite Element (FE)

Parallel Computation of the Saturation Process in a Nonlinear Dynamo Modely the action of the Lorentz force supresses Lagrangian chaos of the flow is checked by direct numerical simulations of the MHD equations. As a measure of the level of chaos the Lyapunov exponent of a set of 128 × 128 trajectories of fluid particles is computed in the linear growth phase of the dynam

Investigation of the Flow Characteristics Occurring in Flame Stabilization Processesed Navier-Stokes equations (RANS). An experimental setup, “ORACLES”, which is a simplified combustion chamber, is selected to study the flow physics. Simulations are performed on unstructured grids using LES and RANS, and on structured grids applying RANS with various turbulence models. To study the

Development of a Parallel Unstructured Multigrid Solver for Laminar Flame Simulations with Detailed ies. The so called . code is based on the . library developed at IWR, Heidelberg. With a view to reducing computational time as much as possible, we combine an appropriate low Mach number modelisation with implicit time integration, Krylov-Newton and multigrid preconditioning, on unstructured, dynam
