Study on Parallel Computation of CFD Problems

摘要

Nowadays LES is the best technique for a wide range of engineering problems due to its application in complex geometry's and phenomenology's e.g. turbulence and combustion, without wasting too much time compared with DNS (Direct Numerical Simulation) and needing less experimental parameters than RANS (Reynolds Average Navier Stokes). LES is based in the Navier Stokes equations filtered in space obtaining the so called Grid Scale values such as velocities, pressure and kinetic energy.
