On the propagation of acoustic waves through temperature inhomogenities in fluide
Original language description
The work deals with the transmission and reflection of plane acoustic waves propagating in temperature-inhomogeneous fluids. It is assumed that the temperature gradient is collinear with the direction of the wave propagation and that the inhomogeneity islocalized in space, i.e., it forms a ?temperature barrier?. An efficient numerical algorithm employing the Riccati equation is proposed for calculation of the frequency-dependencies of the coefficients of transmission or reflection for arbitrary temperature distributions, based on which, their general properties are studied. Further, an inverse problem is studied; it is shown that the distribution of the temperature in a barrier can be calculated from the frequency characteristics of the reflection (transmission) coefficient, an algorithm for which is described.
