Using a finite volume code, the Navier-Stokes equations are solved for a series of flows around spherically blunted cones. These solutions an 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 for 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 Institute of Theoretical and Applied Mechanics case, initial comparisons are made, and the goal is to continue a careful collaboration.
