    Flow visualization of an inscribed gear pump is carried out to grasp the flow structure governed by the deformation and the volume change of the fluid chamber surrounded by the inner and outer trochoid gears. A platelet type of light-reflecting tracer particles "Kalliroscope" is adopted and applied to the visualization of flow patterns using a transparent model of the pump. Upon taking phase-statistic for the time serial images, the dependence of the flow on Reynolds number and the volumetric efficiency is evaluated.
