    In many of the product lines of Mitsubishi Heavy Industries, Ltd. (MHI), fluids such as liquid and air are used. Therefore, understanding the behaviors and characteristics of velocity and temperature distribution in a flow field by actual measurement is the key to improving product performance. One of the technologies for responding to this need is Phosphorescent PIV, for which MHI has been developing applicable technology to product development testing with the cooperation of the National Institute of Advanced Industrial Science and Technology. This method is PIV using thermographic phosphor, which enables the simultaneous measurement of two-dimensional distribution of velocity and temperature. The measurement procedure was verified using a test flow channel and the correlation between the distribution of flow velocity and temperature was evaluated.
