Abstract

A four-beam two-component laser Doppler anemometer (LDA) with a two-dimensional Raman-Nath ultrasonic cell and a spectral-type integral adaptive signal processor has been developed for measuring the components of the mean flow velocity, turbulence energy, and turbulent shear in a gas stratification wind tunnel. The operation of the system and the data reduction are controlled by running custom-made software on an IBM PC with a CAMAC interface.
