WebIn this paper, the HiSA solver’s accuracy for predicting the drag is evaluated using the DLR-F6 benchmark case. This study shows that HiSA’s results are good and comparable to … Web3 Numerical Schemes. The numerical solution of compressible flow equations can be performed using two different approaches (pressure-based and density-based). In Open- FOAM, both approaches are implemented. RhoCentralFoam is a density- based solver and sonicFoam is a pressure-based solver. WebHiSA can be applied to solve fluid flows in the range of Mach numbers from approximately 0.3 to 5, and it is primarily intended for application to external aerodynamics in the transonic and supersonic regimes. Features include: AUSM+up and HLLC shock capturing schemes Non-reflective characteristic-based boundaries screw in ceiling fan

For 0 deg AoA the Hisa solver gives the same results as simpleFoem, but Hisa runs much faster. The meshing is pretty hard, my opinion. However, keep on Foaming. techGuy Posts: 118 Joined: Sat Jun 18, 2024 12:48 am payless shoe mall medford

"WebThe capacity of existing density-based solver is limited due to the only explicit time discretization [4]. On the other hand, the HISA library stands out with its local time stepping, the LU-SGS preconditioner and the GMRES matrix solver, and the flux-vector splitting and flux-differencing in a coupled matrix approach [5].

WebJun 7, 2024 · HiSA is a density-based solver, and as such suitable for the Mach number range of approximately 0.3 -> 5. If the majority of the flow is in that range, it shouldn't matter if you are looking at internal or external flow. That said, as you observe it has not been extensively tested with internal flow. oliveroxtoby Posts: 683 WebApr 11, 2024 · Furthermore, in order to overcome the well-known weakness of the standard OpenFOAM compressible solvers, the newly adapted overset library was integrated with …
