Measurements of the thermodiffusion ratio in a binary solution using an acoustic resonator

  • K. F. ShipilovEmail author


The nonlinear acoustic resonator filled with a layered solution is studied. The possibility of its application to measure liquid parameters is shown. The proposed acoustic method is based on the dependence of the speed of sound in a solution on its concentration which varies due to thermal diffusion in the beam propagation region. An analysis of the relations describing the resonator transmittance showed that, having measured the steady-state and minimum resonator transmittances, the thermodiffusion ratio in a binary solution filling the resonator can be determined.
