Abstract
In this paper, experiments to detect turbulent spots in the transition al boundary layers, formed on a flat plate in a free-piston shock tunn el how, are reported. Experiments indicate that thin-film heat-transfe r gauges are suitable for identifying turbulent-spot activity and can be used to identify parameters such as the convection rate of spots an d the intermittency of turbulence.
