The aim of this paper is the presentation of two simple transient phenomena in compressible fluids. We show two different time-dependent solutions based on Fourier analysis and obtained for an initial temperature perturbation suddenly applied to a gas, in bounded and unbounded 1D domains. In both cases, the linearized field equations yield a non vanishing velocity field which seems to equilibrate the temperature gradient and it disappears when the temperature reaches the equilibrium state.

Abstract
The aim of this paper is the presentation of two simple transient phenomena in compressible fluids. We show two different time-dependent solutions based on Fourier analysis and obtained for an initial temperature perturbation suddenly applied to a gas, in bounded and unbounded 1D domains. In both cases, the linearized field equations yield a non vanishing velocity field which seems to equilibrate the temperature gradient and it disappears when the temperature reaches the equilibrium state.File in questo prodotto:
