Several correlation-based PIV evaluation methods are compared by applying them to the evaluation of simulated PIV recordings, in which the particle images are distributed stochastically and have a Gaussian gray value distribution. The influence of particle image displacement and the influence of interrogation window size on the evaluation accuracy in uniform and in non-uniform flow were investigated. In all these cases the best results in terms of a statistical error are obtained with the MQD method.
