We present a flow visualization technique that provides time-averaged three-dimensional images of stationary multiphase gas—liquid flows in microchannels using X-ray Tomographic Microscopy (XTM). The ability of reconstructing a three-dimensional image of the flow makes XTM a powerful non-destructive investigation method for analysis and study of the flow pattern. Due to several restrictions, this measurement method is applicable for stationary flow patterns only. Comparing the demonstrated XTM results with those obtained by conventional optical flow visualization techniques, XTM is shown to be an adequate flow visualization method for annular flow, which is mostly required in multiphase chemical reactions in microsystems.
