Finite vortex model for use in fluid flow numerical simulation, especially for modeling unsteady flows, whereby a general roll-off model is used to model the finite edge vortex

摘要

Finite vortex model for modeling oscillating structures in fluid flows, without use of complex Navier-Stokes methods. The method is based largely on replacement of the KUTTA condition of current airfoil theory, i.e. smooth flow on the trailing edge, with a general roll-off model for the finite edge vortex.
