An enhanced AUSM $$^{+}$$ + -up scheme for high-speed compressible two-phase flows on hybrid grids

High-speed Compressible Flows about Axisymmetric Bodies

The approximate method for the account of compressibility, which was successfully applied earlier for 2-D problems, is developed for axisymmetric case in the present work. The offered method is analyzed with reference to two mediums: air and water. Comparison of the results of calculations on an offered method and a method of Dorodnitsyn integrate relations has shown acceptable accuracy of the ...

High-resolution simulation of cavitation in compressible two-phase flows

The aim of this research project is to take an existing compressible two-phase flow solver and to turn it into a fully parallelized scalable MPI code capable of simulating three-dimensional geometries at unprecedented resolution with high fidelity to the basic physics. The existing code has been developed by several academics (Stephen Shaw, Xi’an JiaotongLiverpool University, and Peter Spelt, E...

A high-order cell-centered Lagrangian scheme for two-dimensional compressible fluid flows on unstructured meshes

We present a high-order cell-centered Lagrangian scheme for solving the two-dimensional gas dynamics equations on unstructured meshes. A node-based discretization of the numerical fluxes for the physical conservation laws allows to derive a scheme that is compatible with the geometric conservation law (GCL). Fluxes are computed using a nodal solver which can be viewed as a two-dimensional exten...

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...
