Abstract
The objective of this work was to design, analyze and test a high frequency fiber-optic temperature probe and sensor intended for measuring the temperature change as a blast wave formed by a detonation passes over the sensor. The design is based on extensions of an existing fiber-optic temperature sensor created by Luna Innovations Incorporated. A finite element model was created using ANSYS to predict the temperature and material response of the sensor. The results of the model were verified through experiments performed in a shock tube to simulate a blast wave. The shock tube flow environment was also examined through the use of schlieren photographs and CFD using Fluent. The fiber-optic sensor was found to have a shorter response time than a high-speed commercially available thermocouple, and good agreement was shown between the predicted and measured response of the sensor.
