Abstract
We have proposed a novel measurement technique of a time-series 3-D temperature distribution in turbulent flames by using heat radiation from a Hi-Nicalon fiber array. First, we demonstrated measurements of instantaneous 2-D flame temperature distribution by this technique. Then the second step, in this paper, measurement of Time-Series 1-D temperature distribution of turbulent flames is carried out toward completing the time-series multi-dimensional measurement. In addition, we tried to improve the time-response of the system by utilizing the property of the fine wire having first-order time-lag. In compensation procedure for a first-order-time-lag, we used the curve fitting procedure for first-order-time-lag and Fast Fourier Transform/Inverse FFT. As a result, temperature histories with compensation show steeper fluctuation than original one, resulting in an improved time response.
