Paper Abstract

The optical techniques keep a large interest in aerodynamics to visualize the flow in wind tunnels. Beside the fact they are non intrusive, these techniques provide a global view of a large field in the flow which, even if purely quantitatively, helps the aerodynamicist to interpret local measurements performed by a limited number of probes like Pitottubes, hot wires and so on. In this presentation, we intend to show new applications of well known opticals techniques improved by the use of laser light. The first one concernes the holographic interferometry used in the millisecond to microsecond domain to analyse the turbulence in a boundary layer. The second one will show visualization of smoke seeded flows illuminated by a light sheet provided by a laser beam enlarged, in one dimension, by a cylindric lens. This is applied to the study of vortices in the microsecond to nanosecond domain, illustrated by slides and film.
