Abstract
THIS PROPOSAL IS FOR A DESIGN STUDY FOR THE DEVELOPMENT OF A COMPUTER CODE FOR THREE DIMENSIONAL TRANSIENT FLOW PREDICTION. THE COMPUTER CODE WILL BE CAPABLE OF ACCURATELY PREDICTING INCOMPRESSIBLE TRANSIENT TURBULENT FLOW FIELDS USING THE FINITE VOLUME TECHNIQUE. THE CODE WILL BE APPLICABLE TO THREE DIMENSIONAL INTERNAL AND EXTERNAL FLOW PROBLEMS AND WILL BE IN THE FORM OF GENERALIZED CURVILINEAR COORDINATES TO INCLUDE CARTESIAN, CYLINDRICAL, AND SPERICAL SPACE. THE ALGORITHM WILL BE CAPABLE OF PERFORMING BOTH FULLY ELLIPTIC AND ELLIPTIC PARABOLIC ANALYSES. THE TURBULENCE MODEL WILL AT LEAST INCLUDE THE TWO EQUATION K-E METHOD. THE CODE WILL BE COMPATIBLE WITH THE VAX 11/780 COMPUTER, WILL BE FULLY DOCUMENTED, AND BENCHMARKED AGAINST EXPERIMENTS. THE CODE WILL UTILIZE A PREVIOUSLY DEVELOPED USER-FRIENDLY NAMELIST TECHNIQUE FOR PROBLEM DEFINITION AND OPTION SLECTION. THE ALGORITHMS WILL EMPLOY ACCURATE RUNGE-KUTTA TIME INTEGRATION, WILL USE EFFICIENT MULTIGRID METHODS FOR ELLIPTIC EQUATIONS, WILL INCLUDE AUTOMATIC ERROR ESTIMATION, AND WILL INCLUDE THE OPTION FOR SOLUTION ADAPTIVE GRID GENERATION.
