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…
A bound-preserving oscillation-eliminating discontinuous Galerkin method with operator splitting for solving Kapila's five-equation model
Jia-Jun Zou, Yu-Chang Liu, Fan Zhang +3
This paper proposes a robust operator-splitting discontinuous Galerkin (DG) framework to overcome the severe stiffness-induced instabilities in simulating compressible two-phase fl…
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…
