(in color) Processing of data from the DPD simulation of unsteady flow in a pipe: (a) - averaged solution (streamwise velocity component, aligned with the x axis) computed with a standard averaging with Nts = 50; (b) - averaged solution processed with the WPOD; here the data is reconstructed using the first two POD modes. (c) -exact solution. (d–f) - gradients of the streamwise component of the velocity filed.
