Abstract

Phase Doppler anemometry (PDA) suffers from the Gaussian beam effect which causes erroneous particle sizing. This paper studies numerically the Gaussian beam effect by using the computer simulation which is based on the generalized Lorenz-Mie theory (GLMT). Numerical results should be carefully considered in design of the PDA optical configuration.
