Research on the Flow Characteristics of Different Aerodynamic Configurations Based on Water Tunnel Laser-Induced Fluorescence Technology
In the 1m×1m water tunnel of state key laboratory of aerodynamics,laser-induced fluorescence technology is used to conduct experimental research on the flow structure and wake structure of airfoil,swept wing and rotor model.This paper explores the flow characteristics and flow mechanism of the typical aerodynamic configuration from the experimental point of view,and visually demonstrates the laminar flow,transition and turbulence structure of the boundary layer of the typical aerodynamic configuration model,as well as the wake velocity pulsation,vortex formation and evolution process.Through the observation and analysis of the flow characteristics of the typical aerodynamic configuration model,the spatial evolution law of different complex flows along the flow direction and the structural characteristics of the flow profile are revealed,the effectiveness of the laser-induced fluorescence technology in the water tunnel to display multi-scale flow structure is verified.
