Title:
FLUIDITY STATE MEASURING SYSTEM AND FLUIDITY STATE MEASURING METHOD
Document Type and Number:
Japanese Patent JP2006126114
Kind Code:
A
Abstract:

To provide a fluidity state measuring system by a laser Doppler method capable of measuring the fluidity state by particles accompanied by supercritical water without being changed in the supercritical water.

This system has a fluid tank 3 for storing mixed fluid of particles generating scattered light when being hit by laser light and a measuring object fluid, a pump 14 for pressurizing and fluidizing the mixed fluid, a preheating container 7 for preheating the pressurized mixed fluid and generating supercritical fluid, an observation container 9 allowing the supercritical fluid acquired by the preheating container 7 to pass and having a window 10 where the laser light is transmitted, a laser irradiator 11 for irradiating the laser light toward the supercritical fluid through the window 10, and a scattered light detector 12 for detecting scattered light acquired through the window 10. A downward passage is formed on a part where the mixed fluid in the preheating container 7 is changed from liquid into the supercritical fluid.
