| Abstract: | The quasi-steady heat-transfer mechanism of the thin-wall-tube-shaped fiber grating sensor is analyzed according to Fourier's heat-transfer law and Newton's cooling law,and the heat-transfer process is numerically simulated using ANSYS software.The temperature on the inner wall and the outer wall of a fiber grating dual-parameter sensor for determining temperature and pressure is measured in the range of 22.3～303.1℃,.The result shows that the numerical simulation result basically tallies with the measured result.The study result can provide basis for the design and the measurement of the thin-wall-tube-shaped fiber grating sensor. |
