Abstract:

THIS PROJECT FORMULATES, TESTS AND EVALUATES NEW TECHNIQUES FOR IMPROVING THE ACCURACY AND EFFICIENCY OF IMPLICIT FINITE-DIFFERENCE ALGORITHMS FOR THE THREE DIMENSIONAL COMPRESSIBLE NAVIER-STOKES EQUATIONS. THE TECHNIQUES SHOULD, IF SUCESSFUL, REDUCE THE ERRORS DUE TO ADDED ARTIFICIAL DISSIPATION AND WOULD PROVIDE FOR SYSTEMATIC SELECTION OF TIME STEPS TO ACCELERATE CONVERGENCE TO STEADY SOLUTIONS. THE INVESTIGATION FOCUSES ON THE REMOVAL OF DIFFICULTIES WHICH HAVE ARISEN IN THE SOLUTION OF PRACTICAL FLOW PROBLEMS IN THREE DIMENSIONS IN WHICH COMPLICATING FACTORS SUSCH AS SHOCK WAVES AND SEVERELY STRECHED MESHES TO ACCOMADATE VISCOUS EFFECTS ARE PREVALENT. THE GOAL IS TO DEVELOP COMPUTATIONAL TECHNIQUES WHICH WOULD REPRESENT A SIGNIGICANT IMPROVEMENT IN ACCURACY AND CONVERGENCE RATE (EFFICIENTLY) FOR THE THREE-DIMENSIONAL CATEGORY OF FLOWS CONSIDERED.
