Fast modeling method for aircraft wake vortices

The mass,velocity and wing shape of the aircraft decide the intensity of wake vortex.The passive conservative model can better depict the movement evolution rule of water vapor and potential temperature in wake vortices.Since parametric studies are computationally expensive to the large amount of CPU time per simulation.In addition,it can't forecast the state distribution characteristic of any aircraft wake vortex in a real-time manner.Therefore,a fast modeling method for aircraft wake vortex was presented.It has solved the problems,such as the high request for computer time,long simulation time and lack of real time simulation.This can provide a theoretical basis to avoid former airplane's wake vortex and reduce the wake accident.
