DYNAMIC LIFT ANALYSIS

AN INNOVATIVE APPROACH IS PROPOSED IN APPLYING STATE-OF-THE-ART NUMERICAL MODELLING TO THE IMPORTANT PROBLEM OF DYNAMIC LIFT ANALYSIS. UNDER THIS APPROACH AN EVALUATION OF POSSIBLE ALGORITHMS WOULD BE MADE AND THAT ALGORITHM MOST ADVANTAGEOUS TO THE DIFFICULT DYNAMIC LIFE SIMULATION WOULD BE CHOSEN FOR INCORPORATION INTO AN EXISTING NAVIER-STOKES CODE. SIMILARLY, TURBULENCE/TRANSITION MODELS WOULD BE REVIEWED AND THAT MOST APPROPRIATE WOULD BE INCORPORATED INTO THE CODE. THE CODE WOULD BE COMBINED WITH A USER-FRIENDLY WORKSTATION-BASED PROTOCOL TO ALLOW EASY USE BY THOSE NOT EXPERT IN CFD. UNDER THE PHASE I EFFORT, NUMERICAL METHODS AND TURBULENCE/TRANSITION MODELS WOULD BE ASSESSED AND A DEMONSTRATION CASE WOULD BE RUN. THE PHASE II EFFORT CONVERT THE RESEARCH CODE INTO A DESIGN CODE AND DEMONSTRATE THE CAPABILITY THROUGH A SERIES OF SIMULATIONS FOR SUGGESTED FLOW CONTROL TECHNIQUES.
