Direct Numerical Simulation of Liquid Films with Large Interfacial Deformation

Liquid films are important in many industrial applications, but also from a fundamental point of view, they are important two-phase flow systems. In this paper, we develop a sharp interface/level set method for the Direct Numerical Simulation (DNS) of liquid films with large interfacial deformations, and large density ratio between the liquid and the gas phase. We use the ghost fluid method to ...

Numerical simulation of deformation of a metal foam Numerical simulation of deformation of a metal foam

Mathematical model for the description of deformation of a porous metal is constructed on the basis of generalized rheological method. In this method a new rheological element, so-called rigid contact, is used to describe the uniaxial deformation of materials with different resistance to tension and compression. Change in the resistance of a porous metal to external loads, when the collapse of ...

Large Scale Numerical Simulation for Superfluid Turbulence

Large scale numerical simulation of quantum turbulence is performed by using 3-D time-dependent Gross-Pitaevskii equation. The energy spectrum obeying Kolmogorov law and large scale self-similar structure of quantum vortex tangle are found in a fully developed dumped turbulent state. Width of the inertial range becomes large depending on the system size of the simulation that is consistent with...

A Numerical Model for Large Deformation on Meteorological Images

The purpose of non-rigid motion in computer vision is the study of the geometrical deformation that may aaect an object during its temporal evolution. One often assumes that this process is local and continuous; it is therefore the case for local geometrical features, which are considered as relevant for studying deformation. This assumption is no more valid when the structure is widely distort...
