Stability of three-dimensional supersonic boundary layers Conference Paper

abstract

• 1990 American Institute of Aeronautics and Astronautics, Inc. A rotating cone is used as a model of a swept wing in supersonic flow. Linear stability calculations show that the amplification rate of the First mode is increased by a factor of 2 to 4 due to the presence of the crossflow. The most unstable crossflow instability has a nonzero frequency. The second mode in a three-dimensional (3-D) boundary layer is found to be oblique whereas the second mode in a two-dimensional (2-D) boundary layer is 2-D. Cooling is found to be ineffective in controlling crossflow. The correlation of transition location (N=9) with various non-dimensional parameters describing the crossflow profile is discussed.
