Abstract

Recently Hendricks et al [ 1] presented experimental evidence that heat transfer through a near-critical fluid is accompanied by oscillations. No basic explanation of these oscillations has been presented. This paper attempts qualitatively to account for this phenomenon by assuming that the critical state is not unique but rather that there are an entire series of critical states with experimentally distinguishable properties. This is because each critical state has a distinguishable speed of sound which affects the communication of a perturbation through the critical fluid. When communication does take place, it is by a nonlinear wave propagation. A perturbation which is not observable in an ordinary fluid can change a critical fluid from one critical state to an experimentally distinguishable state.
