Thermal flow field imaging in air using T-sensitive PIV particles
Thermographic PIVmarks a real breakthrough for simultaneous flow velocity and temperature measurements, because it works with phosphorescent PIV particles, which are suitable both for PIV and laser induced thermometry measurements with only slightly modified PIV systems. The phosphorescent PIV seeding material comes as a ceramic powder consisting of 2 µm particles showing a temperature sensitive emission after UV laser excitation which is used both for PIV and thermometry. Due to their small size the powder particle rapidly assume the velocity and temperature of the surrounding flow. Time-resolved thermal flow field imaging is possible based onHigh-Speed FlowMaster PIVsystems.
