OPTICAL FIBER PROBE FOR MEASURING LOCAL TWO-PHASE FLOW PARAMETERS, METHOD OF MANUFACTURING THE OPTICAL FIBER, AND METHOD OF MEASURING TWO-PHASE FLOW PARAMETERS

摘要

Disclosed is an optical fiber probe for measuring parameters of a local two-phase flow, which is fixed to a probe holder of a two-phase flow measuring device and is installed in a flow path of a two-phase flow of a liquid phase fluid and a gas phase fluid. The optical fiber probe includes: a first tapered portion which is formed in a conical shape in which a diameter is gradually decreased at a certain ratio in an axial direction thereof to a point spaced a certain distance from a point thereof fixed to a probe holder, toward a leading end of the optical fiber probe; and a second tapered portion which is formed in a conical shape in which a diameter is gradually decreased at a greater ratio than that of the first tapered portion in an axial direction thereof from an end of the first tapered portion.
