Kurzfassung
This paper investigates the use of high-power light emitting diode (LED) illumination in Particle Image Velocimetry (PIV) as an alternative to traditional laser-based illumination. The solid-state LED devices can provide averaged radiant power in excess of 10W and by operating them with short current pulses, considerably higher than in continuos operation, light pulses of sufficient energy suitable for imaging micron-sized particles can be generated. The feasibility of this LED-based illumination for tomographic PIV is demonstrated in this paper by measuring grid-generated turbulence and a cylinder wake flow. Also, the use of LED illumination in time-resolved measurements is discussed.
