A multi-resolution SPH method for fluid-structure interactions
Chi Zhang, Massoud Rezavand, Xiangyu Hu
In this paper, we present a multi-resolution smoothed particle hydrodynamics (SPH) method for modeling fluid-structure interaction (FSI) problems. By introducing different smoothin…
A L2-norm regularized incremental-stencil WENO scheme for compressible flows
Yujie Zhu, Xiangyu Hu
For the simulation of compressible flow with a broadband of length scales and discontinuities, the WENO schemes using incremental stencil sizes other than uniform ones are promisin…
Spot the Difference: Accuracy of Numerical Simulations via the Human Visual System
Kiwon Um, Xiangyu Hu, Bing Wang +1
Comparative evaluation lies at the heart of science, and determining the accuracy of a computational method is crucial for evaluating its potential as well as for guiding future ef…
A Consistent Parallel Isotropic Unstructured Mesh Generation Method based on Multi-phase SPH
Zhe Ji, Lin Fu, Xiangyu Hu +1
In this paper, we propose a consistent parallel unstructured mesh generator based on a multi-phase SPH method. A set of physics-motivated modeling equations are developed to achiev…
Dual-criteria time stepping for weakly compressible smoothed particle hydrodynamics
Chi Zhang, Massoud Rezavand, Xiangyu Hu
Implementing particle-interaction configuration and time integration are performance intensive essentials of particle-based methods. In this paper, a dual-criteria time-stepping me…
A weakly compressible SPH method for violent multi-phase flows with high density ratio
Massoud Rezavand, Chi Zhang, Xiangyu Hu
The weakly compressible SPH (WCSPH) method is known suffering from low computational efficiency, or unnatural voids and unrealistic phase separation when it is applied to simulate…
