Abstract
Aerosol-deposited thermographic phosphors can be used for non-contact, two-dimensional temperature sensing in extreme environments. The fast response time and thermal/environmental stability of doped ceramic powders allow for temperature measurements up to the melting point of the phosphor on hot surfaces, such as rapidly rotating turbine components and combustors.
Claims7
A method for measuring the temperature of a surface, comprising:
- aerosol depositing a thermographic phosphor on a surface,
- heating the surface to a temperature, and
- measuring the temperature of the deposited thermographic phosphor using a phosphor thermometry method.
