Title: Progress in Velocity Field and Density Field Measurement Technologies for Compressible Flows

Abstract:

Hypersonic flow and combustion flow are typical compressible turbulent flows, characterized by three-dimensional compression effects and a large dynamic range of velocity. Accurate measurement of velocity fields and density fields is crucial for improving the aerodynamic performance of aircraft and combustion efficiency of je engine. This report will introduce the recent progress made by the Beihang research team in the measurement technologies for velocity fields and density fields of compressible flows, including deep learning optical flow algorithms, neural network spatial calibration models, neural network particle reconstruction algorithms, three-dimensional particle tracking technology, and three-dimensional density field reconstruction technology based on background schlieren technology.
