Abstract

An experiment is described in which the instantaneous three-dimensional gas-concentration distributions in turbulent jets and flames were recorded. A resonant scanning mirror was used to sweep a laser sheet through the volume of a flow field. During the 1.4-μsec duration of the laser pulse, an electronic framing camera imaged the scattered light from the gas in as many as 12 parallel planes within the flow. A two-dimensional charge-coupled-device array was used to digitize the images from the framing camera in real time. The measurement period was brief enough to freeze the motion of the gas.
