AI Technical Summary
Existing technologies struggle to achieve high-resolution simultaneous measurement of the phase state and temperature distribution of two-phase flows under high temperature and high pressure conditions. Furthermore, existing equipment is complex, expensive, has low spatial and temporal resolution, and poses radiation safety risks and flow field intrusion effects.
Employing a fiber-optic-wire mesh composite emitter design, the device achieves high spatiotemporal resolution measurement of two-dimensional phase field and temperature field distributions through synchronous excitation and detection of electrical and optical signals. It utilizes a sensor with a grating and metal cladding etched into the fiber core, combined with rigid signal connection lines and an insulating ceramic internal flow channel, ensuring the device's sealing reliability and measurement accuracy under high temperature and pressure.
It achieves simultaneous measurement of phase field and temperature field, ensuring accurate correspondence of measurement results in time and space. It has millimeter-level spatial resolution and millisecond-level temporal resolution. The equipment is simple, safe, adaptable to high temperature and high pressure environments, low intrusiveness, and has no radiation risk.
