Efficient Simulation and Novel Modeling by Using Generic Three-Dimensional Exact Solutions to Analyze Transport Dynamics in Turbulent Vortices

Abstract

In this project, we have formulated an alternative boundary-layer theory. This new analysis will be able to mathematically describe flow-separation unlike the classical theory. In our research, we have partially validated the developed theory and concluded that approach has considerable potential to account for flow-separation. The effective description of separated flow can potentially lead to a fast simulation-algorithm for aerodynamic computation. Our estimate predicts that this semianalytical scheme will compute the lift and drag on an aerodynamic body in less than O.lsec with less than l\% relative error. This is more than hundredfold increase over current simulation-efficiency. The enhanced efficiency will enable hitherto impossible exploration of new designs for maximization of the lift to drag ratio. In the future, this will revolutionize aviation technology by the development of bio-inspired aviation mechanism and other novel systems. Such improvements will help in energy-savings and pollution control by reducing fuel consumptions.
