Abstract

We present preliminary results of the measurement of temperature distribution fields of a synthetic jet produced by a Helmholtz resonant cavity when used for the cooling of an aluminum plate. The plate is set at 80 °C and background- oriented schlieren images are registered by a high speed camera at 2000 fps. The background consists of sinusoidal fringes printed on a transparent slide and it is back-illuminated by a matrix of 20 3-W white LEDs. A reference image is taken with no jet and a series of images are then recorded with the cavity working in the first resonance frequency, 125 Hz. The observation region corresponds to an area of 1 × 10 cm2. Results show an oscillatory behavior of the temperature distribution at the resonant frequency.
