Flomix - Codes
Within the project the two Computational Fluid Dynamic Codes CFX and FLUENT are used. The main aim is to justify the application of various turbulence and turbulent mixing models for different flow conditions. Also, the numerical diffusion should be suppressed and the grid, the time step and the user effects should be decreased in the CFD analyses.
