The present study is focused on two topics: - The implementation of an approximate Riemann solver for the so-called arti cial compressibility method for solving the Navier-Stokes equation with temperature and viscous terms on a structured Cartesian grid; and - The implementation of explicit register allocation in order to see if by these means improvements in cache memory access and the expected speed improvements can be realized.enApproximate Riemann SolverRoe SolverFinite Difference MethodIncompressible flowsThesis
