In the paper we develop Random Vortex Blob method for the case of flows
in periodic domains. It is shown how the formulation of the problem must
be modified to account for the periodicity constraint. Properties of periodic
vorticity particles are discussed. We also derive a rigorous method to
satisfy the boundary conditions. Example computations concern the flow
in an X-periodic duct with moving boundaries and varying in time pressure
gradient.
