A multiphysics framework for compressible and incompressible flow, aeroacoustics, and combustion phenomena.
Computational fluid dynamics, computational aeroacoustics, conjugate heat transfer, flows with combustion, particulate flows.
The multiphysics framework ZFS is developed at the Institute of Aerodynamics at RWTH Aachen University, Germany since 2004. It is used to simulate compressible and incompressible flow, aeroacoustics, and combustion phenomena for various fundamental, technical, and biofluidmechanical problems. It uses hierarchical Cartesian grids with a quadtree/octree structure and supports solution adaptive mesh refinement as well as flows with immersed moving boundaries.
For the High-Q club, the computational aeroacoustics component of ZFS has been evaluated on JUQUEEN. It uses a high-order discontinuous Galerkin method for the spatial discretization of the acoustic perturbation equations and a fourth-order Runge-Kutta scheme for integration in time to solve for the aeroacoustic pressure field.
