In this report, in order to evaluate influence of pad shape on the behaviour of Taylor vortices in submerged multi-pad journal bearings, fluid film flow in bearing clearance and fluid flow between pads were visualized experimentally. Critical Taylor number decreased with an increase of pad spacing irrespective of pad shape. Two-dimensional flow field between pads were measured by Particle Image Velocimetry. In the case of streamlined pads, fluid flow entered rear pad fluently.
