Abstract:

Hot-wire surveys were conducted across the wake behind a magnetically-suspended, 10 deg. half-angle cone of 1 in. base diameter in the Mach 16 helium wind tunnel, both at the unit Reynolds numbers 120,000 and 270,000. At the higher Reynolds number, transition was observed at approximately 8 diameters downstream. The turbulent fluctuations were limited in the region near the outer edge of the wake, spreading out at an extremely slow rate. Author
