Turbulent fluid-structure interaction of water-entry/exit of a rotating circular cylinder using SPH method

Abstract: This paper studies the two-dimensional (2D) water-entry and exit of a rotating circular cylinder using the Sub-Particle Scale (SPS) turbulence model of a Lagrangian particle-based SmoothedParticle Hydrodynamics (SPH) method. The full Navier-Stokes (NS) equations along with the continuity have been solved as the governing equations of the problem. The accuracy of the numerical code is veri¯ed using the case of water-entry and exit of a nonrotating circular cylinder. The numerical simulations of water-entry and … Show more

“…SPH is a mesh-free Lagrangian particle-based method, which was initially developed by Gingold and Monaghan 31 for astrophysical problems. However, it had been used for simulating a broad range of physical problems including free surface, [32][33][34] turbulent, 35,36 multi-phase, 15,37,38 heat transfer, 39,40 and biological problems. 41,42 In this section, the SPH method is described in more detail, which is used in our simulation.…”

“…One of the alternative is to use a mesh-free method such as the SPH scheme. The SPH method is a mesh-free Lagrangian particle-based method and is proved to be applicable for the simulation of multidimensional complex geometries, deformable materials or moving boundaries [37], non-Fourier nanoscale applications [38], and solving the Poisson's problem [39].…”

“…Many challenging fluid and solid mechanics related problems have been successfully handled with the SPH methods, which for instance include free surface flows, [18][19][20] nano- 21 and bio-heat transfer, 22 multi-phase flow, 23 electrohydrodynamics (EHD), [24][25][26] among others. However, to the best of our knowledge, an attempt for simulating active nematics with the SPH method has not been realized to date.…”
