Scaling Analysis on the Dynamic and Instability Characteristics of Isolated Wingtip Vortex

What is it about?

As a canonical trailing vortex, the wingtip vortex contains many fundamental problems and produces various adverse effects that remain difficult to control. Understanding the dynamics, formation, and instability of wingtip vortex is of particular importance and essential to help engineers explore effective flow control strategies. However, the instability evolution of the wingtip vortex still has much-remained questions due to the existence of long-wave instability, short-wave instability, and vortex wandering. In this situation, the investigation of a scaling law to describe even predict the development of instability characteristics along with the streamwise location is necessary and significant.
