Abstract :
Thermoacoustic oscillation in a helium circulation system is a serious problem to its performance. From a perturbative analysis to the conservative laws on the helium flow, it has been shown that the zeroth order temperature plays an important role on both oscillation and steady flow. From the analysis and an evaluation of the thermal radiation from the environment, the estimation method of the internal fields from the boundary measurements has been derived.
