Laminar flow measurements in a square duct using laser Doppler anemometry
Abstract
A laminar water flow facility has been designed to enable fully developed flows in the Reynolds number range from 45 up to 1250 to be investigated. Experimental measurements have been obtained using laser Doppler techniques and the results compared with those obtained using both finite difference and boundary element techniques. The correlation between experimental and analytical results is good, the use of boundary element techniques significantly reduces the number of equations to be handled in the computer. The method therefore offers a very powerful tool for analysis of multidimensional flow problems involving any complex geometry and boundary conditions.
