説明
An ultrasonic CT method was proposed for a new type of indirect thermometry, and its applicability was demonstrated for measuring the temperature distribution of liquid layer. An axis -symmetrical temperature field of a coaxial jet flow was chosen as the objective field to check the validity of the proposed thermometry. Temperature dependence of sound velocity in an isothermal pure water was preliminarily measured by an ultrasonic pulse technique.<BR>Cross-sectional distribution of sound velocity in the coaxial jet flow, obtained from a two-dimensional Fourier transform (TFT) method using propagation times measured by the ultrasonic pulse technique, was transformed into the temperature distribution, taking account of the predetermined temperature dependence of sound velocity.<BR>The reconstructed temperature distribution thus obtained acoustically was compared, with measurements by the existing thermocouple method. The reconstructed temperatures were a little different from the measured ones in the vicinity of the center of the cross section, but a relative comparison of these two distributions showed that the former was comparable to the latter.
