The present paper offers a numerical model which can be applied for the simulation of wave height distribution on a 2-D horizontal soft mud layer. The model is based on mild slope equations and it includes combined wave refraction, diffraction, reflection and breaking. The high energy dissipation of wave height due to the presence of fluid mud layer has also been simulated. Wave height attenuat...

We explore possible applications of the Lattice-Boltzmann Method for the simulation of geophysical flows. This fluid solver, while successful in other fields, is still rarely used for geotechnical applications. We show how the standard method can be modified to represent freesurface realization of mudflows, debris flows, and in general any plastic flow, through the implementation of a Bingham c...

Simulations of viscoplastic materials are traditionally governed by continuum mechanics. The viscous behavior is typically modeled as an internal force, defined by diverse quantities. This work introduces a fluid model to simulate the viscoplastic effect of solid materials, such as plastic, wax, clay and polymer. Our method consists in modeling a solid object through a non-Newtonian fluid with ...

background: replacement of the lost tissue is the major concerns of the plastic surgeons. expanded area should be coherent with the surrounding tissue. tissue expansion technique is the reforming methods the skin tissue scarcities. several methods for tissue expansion are available; including usage of silicon balloon and injecting fluid into the tissue expander. materials and methods: in a clin...

I obtained my Bachelor’s degree from Peking University. For my Bachelor’s thesis, I implemented the residual-free bubble method for advection dominated convection-diffusion problem. My primary research area as a Master’s student was on fluid simulation. My advisor and I developed a continuum plastic fluid model for simulating sand flow. Without having to handle millions of collisions, our solut...

numerical modeling of machining processes is of significance in the parametric analysis and optimization of their performance. in this paper, a finite element-based model of abrasive waterjet (awj) cutting of a ductile material is presented with the help of an explicit, nonlinear finite element method. in this model, both solid-solid interaction and fluid-structure interaction are considered. t...

hydro-forming is a fabrication process that uses a fluid medium to form a piece by using high internal pressure. in tube hydro-forming, a tubular blank is placed between two dies, sealed and pressurized water injected, deforming the tube walls in the cavity form of the dies. exist several typical hydro-forming processes such as t- shapes, cross-shapes and y- shapes. successful hydro-forming dep...
