Performance Analysis of Fiber Optic Sensing Mandrel for Underwater Acoustic Signal with ANSYS

Prashil M. Junghare, Cyril Prasanna Raj P, T. Srinivas: Performance Analysis of Fiber Optic Sensing Mandrel for Underwater Acoustic Signal with ANSYS. In: International Transaction on Engineering and Science (ITES), 1 (1), pp. 23-29, 2018.

Abstract

The proposed paper outlines the design and development of fiber optic sensor using principle of interferometry. In the design, optical light waves are used to extract information. Two parallel mandrels are used where one is the sensing mandrel and another is the anti-sensing mandrel. The mandrel is designed underwater to detect acoustic pressure. Sensing mandrel is referred to as hydrophone which detects the sound underwater. The optical hydrophone is made up of different materials. The different materials used are elastic foam layer, polyurethane, aluminum and nylon. The hydrophone is suspended 200 meters below water surface. The physical properties of the sensing mandrel are varied to select the design that gives optimum minimal sensitivity. The hydrophone is also referred to as fiber optic mandrel since optical fiber is wound on the mandrel. The design is made using ANSYS 12.0, EDA tool. The sensitivity obtained is -64.92 dB for a pressure of 2 MPa.
