A Free Sphere Reverses the Rebound Direction of a Near-Wall Cavitation Bubble
Chun-Zhu Ren, Jun Wen, Hai-Bao Hu +2
A near-wall cavitation bubble is generally expected to acquire a wallward Kelvin-impulse bias and to rebound or jet toward the wall. Here we show that this canonical direction can…
Moving mesh FSI approach for VIV simulation based on DG method with AMR technique
Jia-Jun Zou, Yun-Long Liu, Qi Kong +1
Vortex-induced vibration (VIV) remains a fundamental yet computationally challenging problem in computational fluid dynamics (CFD). This study develops a moving mesh Fluid-structur…
An unstructured block-based adaptive mesh refinement approach for explicit discontinuous Galerkin method
Yun-Long Liu, A-Man Zhang, Qi Konga +3
In the present paper, we present an adaptive mesh refinement(AMR) approach designed for the discontinuous Galerkin method for conservation laws. The block-based AMR is adopted to e…
A theoretical model for compressible bubble dynamics considering phase transition and migration
A-Man Zhang, Shi-Min Li, Run-Ze Xu +3
A novel theoretical model for bubble dynamics is established that simultaneously accounts for the liquid compressibility, phase transition, oscillation, migration, ambient flow fie…
