摘要

In this contribution we investigate the development of turbulent spots in supersonic boundary layers by means of direct numerical simulations. The spot structure is analysed and mean velocity profiles and Reynolds stresses are determined applying ensemble averaging over many simulations. The near field of the spots reveals waves propagating away from the spot in semi-circular patterns. Spot characteristics such as the approximate self-similarity and the resulting spreading angle and effects of Mach and Reynolds numbers are discussed and compared with results from literature.
