Navier-Stokes Simulation and Measurement of Cone Drag at M∞ = 7.9
Abstract
The calculation of a M ∞ = 7.9 flow around a 30° cone in a shock tunnel is presented. It starts from the initial reservoir conditions obtained in the experiment in front of the nozzle. The nozzle flow is calculated using axisymmetric Euler equations, while the model flow is simulated by solving the Navier-Stokes equations. The results of this unsteady calculation are presented as plots of the Pitot pressure and velocity within the test section, as pressure contour plots around the cone at different instants and as plots of the friction drag, form drag and the drag coefficient. The latter is compared with an experimental result. The numerical procedure is described and the results are discussed in detail.
