Towards isolated roughness induced boundary layer transition at supersonic speeds (2024)
Journal Article
González, L. E. M., & Dakka, S. M. (2024). Towards isolated roughness induced boundary layer transition at supersonic speeds. International Journal of Scientific and Technical Research in Engineering, 9(2), 1-16

The height of surface roughness elements affects the onset of laminar to turbulent transition in a boundary layer. CFD studies have been accomplished using RANS models at very low speeds, as a first step towards the understanding of this technology i...
