Solution Acceleration and Accuracy Improvements for Navier-Stokes Solvers

There are two competing goals in computational fluid dynamics: high solution accuracy, and low computational cost. In the present research, three major tasks were performed to improve the solution accuracy and increase the convergence of steady-state solutions: (1) investigate the sources of inaccuracies and the causes of slow convergence, (2) develop new algorithms that eliminate these problems, and (3) combine different solution acceleration techniques to produce a robust and efficient flow solver.
