The author previously presented a method of eliminating undesirable width of characteristic values such as the amplitude ratio and the phase shift peculiar to the former analyzing methods by taking into consideration the heat exchange between fluid and wall of transmission line. To facilitate the description of dynamic characteristics, however, the fundamental equations were too much simplified as exemplified by the assumption of one-dimensional flow in the line.
Here, the basic differential equations are given by the velocity and temperature distribution of the fluid in a cross-section of the transmission line and the dynamic characteristics are analyzed by the above-mentioned method.
Frequency characteristics derived from this method are compared with the experimental results and a good agreement have been obtained.
