Measurement of local voidage in oil/air two-phase flow system

摘要

The paper explains the theory of fiber-optical sensor and its application in measuring the local voidage in oil/air two-phase flow.In order to test the measurement result of the fiber-opticla sensor,we designe dan oil/air circular flow experimental facility equippe dwith measuremnet section of fiber-optical sensor.the results obtained are of great significance in improving the structure,installemnt and experimental method of the sensor.
