Development of 3D Printable Temperature-Sensitive Paint for Micro-channel Application

Temperature-sensitive paint (TSP) has attracted attention in the thermo-fluid science fields as a global temperature measurement technique. It has been utilized to measure a 2-dimensional temperature field on a surface of interest. Those measured temperature fields are used to analyze temperature control systems or thermal properties of aerodynamic objects. The present research focuses on the study of micro-channel flow using a TSP. If the TSP can be applied to a desired cross-sectional region of interest, the heat-transfer between the channel and the surroundings at any desired region can be extracted. A 3-dimensional (3D) and printable TSP is introduced in this study. A 3D printer has been utilized to create a TSP layer at any desired region of an 3D object. The current status of this research will be presented.
