DTNSRDC Three Component Laser Doppler Velocimetry: Mean Velocity Data Analysis.

Abstract

This report describes how the columinous amount of data from Laser Doppler Velocimetry (LDV) experiments can be distilled to produce useful and comprehendable results. The procedures draw heavily on the experience and development work done in implementing three component LDV systems for the towing tanks and large wind tunnels of the David Taylor Naval Ship Research and Development Center. The standard procedures and computer software described are meant to reduce the time needed to analyze and report LDV experiments. The procedures address data collection, data calibration, measurement error estimation, data display graphics, and short and long term data storage. Keywords: Experimental techniques; Velocity measurements; Laser doppler velocimetry; Fluid flow; Error analysis; Three component fluid flow.
