Effects of particle arrival statistics on laser anemometer measurements
Abstract
The effects of particle arrival statistics on the Laser Doppler Anemometer (LDA) measurement of a highly turbulent nonreacting gaseous flow have been investigated. In this study, the flow field of a centerbody combustor was examined. For the flow condition chosen, a recirculation zone, established in the wake of the centerbody, extends about one centerbody diameter downstream. This flow configuration consists of a step shearlayer, a recirculation zone, free mixing layers, and boundary layers. Therefore, it allows the examination of particle arrival statistics for various flow regions having high turbulence intensities.
