Abstract

This paper introduces the generation and influence of the wake, gives the evolution and dissipation model of the wake, analyzes the force of the rear machine into the front machine, and uses the former B747 and the rear B737 as examples, using MATLAB to the front wake vortex. The flow is calculated, and the wake dissipative empirical model is used as the dissipative model for the analysis. The current wake interval is analyzed to prepare for a safe and efficient approach wake interval. The simulation results show that the different dissipation rates have different effects on the wake, and the higher the dissipation rate, the smaller the interval required by the front and rear machines.
