This paper focuses on the application of the fast imageprocessing to the internal flow field characterization, andon the set up of the experimental methodology whichenables the use of direct visualization techniques to fluidpower components. More in details, the design of both alow pressure hydraulic power unit and a number ofpolymethyl-methacrylate (PMMA) transparent prototypesare firstly outlined.Afterward, the fast image processing is involved and, tohighlight the usefulness of the fast image processing inthe analysis of multi-phase multi-component effluxes,solid particle injection and air bubble inoculation areused.Finally, some of the results obtained using aprogressive, mid resolution, high frame rate andmonochrome digital camera are shown, and the internalflow evolution is qualitatively analyzed.
