Thermal transpiration (thermal creep) flow, which is induced only by temperature gradient along a channel, is one of the most interesting phenomena in micro gas flows. The thermal transpiration flow has been studied both numerically and experimentally; however, the detailed condition inside a channel has not been enough studied experimentally, and it makes difficult to compare numerical and experimental results directly. In this study, the pressure distribution on a micro channel surface in thermal transpiration flow was measured by means of the Pressure-Sensitive Paint (PSP) technique. And the pressure distribution was a convex profile along the channel.
