Abstract
This paper presents parallelized, solution adaptive, multi-grid hybrid unstructured methods to the turbulent flows past complex configurations. The numerical techniques are accomplished by parallel computing algorithm with multi options of serial, PVM or MPI to accommodate any type of machines, hanging node solution adaptation, algebraic multi-grid speeding-up convergence method. With the enhancement of higher order scheme data reconstruction, higher order upwind-biased differencing, multi-pressure-correction, and Bi-CGSTAB and GMRES matrix solvers, the proposed methods can efficiently and accurately handle flow problems in several cases including benchmark and practical. Very good convergence and accurate solutions have been demonstrated even for complex 3D configurations under high Reynolds number turbulent flow conditions.
