Title: 

Phosphor-based Luminescent Sensor for High-Speed Aerodynamics

Abstract:

High-speed aerodynamic phenomena have not been well understood due to limitations in high-fidelity experimental data that lead to numerical and analytical modeling. Here, we investigated the properties of thermographic phosphors to obtain experimental data with high spatiotemporal resolution in the high-temperature region from 100 °C (373 K) to 800 °C (1073 K). The thermographic phosphor must have sufficiently high-temperature sensitivity and luminescence intensity in the test temperature range. In addition, the binder for thermographic phosphors must be strong enough to withstand supersonic flow and high-temperature environments. The current status of the sensor development is given in the presentation. The application of the sensor is not limited to high-speed aerodynamics. It can be applied to different disciplines that need spatial-temporal measurement under high-temperature environments. The presenter is open to discussing other potential fields for the sensors to be applied.
