Smoke visualization of subsonic and supersonic flows
Abstract
The techniques and facilities developed by Brown for smoke flow visualization at low speeds, and extended by Goddard for high speeds are reviewed. The transition process of the boundary layer on a tangent ogive nose cylindrical body at zero pressure gradient is described noting the influence of an adverse pressure gradient. Studies concerning the effects of sound on the laminar wake behind airfoils and flat plates with sharp leading and trailing edges are outlined. Photographs made with a modified schlieren system are presented, showing flow through a shock wave and expansion around a corner.
