Optical Fibre Fabry-Perot Interferometers for Calorimetric Heat Transfer Gauges

Abstract

A heat flux measurement system comprising a laser diode, a single mode optical fibre interferometer and passive optical fibre components has been constructed. The system has been designed for use in transient flow wind tunnels and has a resolution of 1 kWm/sq meter, a dynamic range of 20 MW m/sq meter and bandwidth > 100 kHz. Heat flux measurements have been made with the system on the endwall of a cascade of stator blades. Optical fibre, Heat flux.
