Summary
In recent years, advances in computer technology have provided the means for more efficient and accurate evaluations of complex computational fluid dynamics (CFD) problems, while better numerical schemes enhance this concept. In this paper acceleration techniques such as parallel processing and agglomeration multigrid are presented. The proposed methodologies are implemented on a family of CFD solvers, called Galatea and Galatea-I, which employ the Reynolds-Averaged Navier-Stokes equations for the simulation of compressible and incompressible flows, respectively. The proposed algorithms are validated against benchmark test cases, concerning the compressible flow over the NASA Common Research Model and the incompressible flow over the DARPA SUBOFF submarine hull.
