Numerical-Experimental Comparisons of Second-Mode Behavior for Blunted Cones Conference Paper uri icon

abstract

  • Using a finite-volume code, the Navier-Stokes equations are solved for a series of flows around spherically-blunted cones. These solutions are used to perform linear-stability analyses to determine the growth of second-mode disturbances. Two cases are investigated: the Stetson experiment, and a recent experiment conducted at the Institute of Theoretical and Applied Mechanics in Russia. Comparisons are made with both basic-state and disturbance-state quantities. For both cases, linear-growth regions are identified. For the Stetson case, using an experimentally-determined wall-temperature distribution for the basic-state appears to give better agreement with the experimentally-measured growth than does the classical adiabatic-wall boundary-condition. For the ITAM case, initial comparisons are made and the goal is to continue a careful collaboration.
