Abstract

Gas flows through a micro-channel were experimentally studied by using PSCC (Pressure-Sensitive Channel Chip). PSCC is a micro-channel fabricated by PDMS containing a pressure-sensitive dye, and then it works as both a micro-channel and PSP (Pressure-Sensitive Paint). The micro-channel (PSCC) with 200 × 91 μm cross section and 2.0 mm long was fabricated. The pressure distribution with the inlet and outlet pressures of 101 kPa and 30 kPa was successfully measured. The measured pressure distribution indicates that the gas flow near the exit of the channel should be treated as compressible flow and the gas flow was choked at the end.
