请问哪位朋友用过AQUILON CFD Code

penglining

The Computational Fluid Dynamic (CFD) library Aquilon, developed in the TREFLE laboratory, is based on a fixed Eulerian grid framework in order to avoid the numerical complexity of Lagrangian grids when dealing with interfacial or free surface flows. This modelling approach, which consists of solving the Navier-Stokes equations, involves the introduction of a new variable for repairing the different phases, the phase function C. It requires the extension of the momentum equations to an Eulerian two-phase flow modelling. In this section, attention will be paid to describe the physical model dedicated to free surface flows. The originality of the numerical methods is then detailed. The numerical tool is well suited to deal with strong interface deformations occurring during wave breaking, for example, and generally with turbulence modelling in the presence of a free surface. The method is able to calculate complex flows in complex geometries. The drawbacks are the numerical diffusion, induced by the numerical schemes used to discretize and solve the equations, and the considerable CPU time, which can be very time consuming when three-dimensional problems are tackled. Nevertheless, this method gives access to much reliable information about the velocity, acceleration and pressure fields under the broken waves.
