A compressible multi-scale model to simulate cavitating flows

A Two -Step Modification toward Implementing Compressible Source Terms in Low Compressible Flows

Multi-scale modeling of compressible multi-fluid flows with conservative interface method

One important issue associated with the complexity of dynamically evolving material interface is the scale-dependent dynamics which implies very different physical phenomena depending on the resolvability of the material interface. In this work we present a concept of multi-scale modeling where the interface interaction is modeled as being in mechanical non-equilibrium or in equilibrium, depend...

A multi-material flow solver for high speed compressible flows

This paper describes a three-dimensional Eulerian-Lagrangian method for the modeling and simulation of high-speed multi-material dynamics. The equations for conservation of mass, momentum, and energy are solved on a fixed Cartesian grid using a fully conservative higher order MUSCL scheme. The dilatational response of each material is handled using a suitable equation of state. The embedded int...

MULTI PHASE COMPUTATIONAL FLUID DYNAMICS MODELING OF CAVITATING FLOWS OVER AXISYMMETRIC HEAD-FORMS

 In the present paper, partial cavitation over various head-forms was studied numerically to predict the shape of the cavity. Navier-Stokes equations in addition to an advection equation for vapor volume fraction were solved. Mass transfer between the phases was modeled by a sink term in vapor equation in the numerical analysis for different geometries in wide range of cavitation numbers. The r...

Using CellML with OpenCMISS to Simulate Multi-Scale Physiology

OpenCMISS is an open-source modeling environment aimed, in particular, at the solution of bioengineering problems. OpenCMISS consists of two main parts: a computational library (OpenCMISS-Iron) and a field manipulation and visualization library (OpenCMISS-Zinc). OpenCMISS is designed for the solution of coupled multi-scale, multi-physics problems in a general-purpose parallel environment. CellM...
