摘要：

A Numerical Analysis is conducted to investigate the Leading Edge Vortex (LEV) dynamics of an elliptic flat plate undergoing 2 dimensional symmetric flapping motion in hover. The plate is modeled with an aspect ratio of 3 and a flapping trajectory resulting in Reynolds number 225 is studied. The leading edge vortex stability is analyzed as a function of the non dimensional formation number and a voracity transport analysis is carried to understand the flux budgets present. The LEV formation number is found to be 2.6. The results of voracity analysis show the highly three dimensional nature of the LEV growth for an elliptic geometry.
