In several contexts, it can be much more effective to couple an SPH solver to another numerical solver, thus enhancing the capabilities of both methods within their specific application fields. In this way, a wider range of problems is efficiently addressed. The coupling algorithm and the related...

The resultant solver can then overcome difficulties with relative/large motions as well as mesh generation in comparison to those when using a moving mesh. However, it handles hydrodynamic problems including viscous free surface flow interaction with a free rigid body. Changes arise from using more ...
Finally, the density-based solver was used for the iterative solution process until convergence. The nozzle cross-sectional temperature and N2 velocity distribution programs calculated by the computational fluid dynamics (CFD) software Fluent (ANSYS 2022 R1) are shown in Figure 5a. Figure 5b shows ...

The evolution of the concentration equation was added to the velocity-verlet time-integration scheme of the fluid solver. Similarly to a predictor-corrector approach, the concentration of each SPH particle was advanced as follows: 𝐶𝑛+12=𝐶𝑛+0.5Δ𝑡(d𝐶d𝑡)𝑛Cn+12=Cn+0.5Δt...
To calculate the subsonic and supersonic conditions reached according to the operational point the density-based solver is selected [36,37]. Furthermore, the Weiss-Smith preconditioned Roe’s Flux Difference Splitting (ROE FDS) scheme is chosen for evaluating inviscid fluxes in the coupled flow ...
The numerical testing of the proposed physically-based incremental constitutive model is conducted for the first time by its implementation in a commercial FE solver and the subsequent simulation of the axisymmetric compression tests. The parameter chosen for the comparison of the simulations and experime...
