摘要
A new ultrasonic method for fluid property measurements is described. The method uses ultrasound to generate acoustic streaming in a fluid. The resulting flow velocity will vary due to several viscous parameters of the fluid. If there are acoustic scatterers in the fluid, it will be possible to monitor the resulting flow velocity with an ultrasound Doppler device. The same acoustic energy is then utilized both to generate the acoustic streaming in the medium and to measure the resulting flow. The method seems to be very well suited for monitoring biological processes. Of special interest, for measurements on contaminated blood or on fluids in a fermentation process, is the method's ability to investigate liquids in a completely closed vessel.
