Optical probe for high-temperature local void fraction determination

The optical response of a high-temperature and pressure-local void fraction device was optimized using a 2-D light ray tracing computer simulation. Snell's law, Beer's law for absorption, and Fresnel laws for reflection and refraction were included to simulate the optics associated with a...

Description
Summary:The optical response of a high-temperature and pressure-local void fraction device was optimized using a 2-D light ray tracing computer simulation. Snell's law, Beer's law for absorption, and Fresnel laws for reflection and refraction were included to simulate the optics associated with a diamond-tipped optical void probe. Based on an optimal design obtained from the computer simulation, an actual diamond-tipped optical void fraction device was constructed and tested at low pressure in air/water flows.
