METHOD FOR INSTANTANEOUSLY MEASURING VOID FRACTION IN FLOW PATH CONTAINING GAS-LIQUID TWO-PHASE FLOW

摘要

PROBLEM TO BE SOLVED: To provide an impedance type void fraction meter instantaneously measuring average void fraction in a cross section of a flow path. SOLUTION: With this method, void fraction variation in a flow path containing gas-liquid two-phase flow is instantaneously measured by providing a center line electrode in the flow path installing a plurality of rods and metal made wall electrode on the wall in the flow path and measuring electric resistance in the flow path.
