摘要：

Some application examples of cross-correlation algorithms for the analysis of high-speed gas-plasma flows and liquid flows are considered. The density fields of transparent media (background oriented schlieren technique) and velocity vector fields of gas-plasma and liquid media were investigated using both particle-based and seedless velocimetry. It is shown that, although the physical fundamentals of measuring the flow fields are different, the same post-processing techniques can be applied. The problems related to the measurements of flow parameters near shock and blast waves are discussed. © 2018 Elsevier Ltd
