This paper focuses on acoustic streaming free jets. This is to say that progressive acoustic waves are used to generate a steady flow far from any wall. The derivation of the governing equations under the form of a nonlinear hydrodynamics problem coupled with an acoustic propagation problem is made on the basis of a time scale discrimination approach. This approach is preferred to the usually invoked amplitude perturbations expansion since it is consistent with experimental observations of…

Wave-Flow Interactions and Acoustic Streaming

The interaction of waves and flows is a challenging topic where a complete resolution has been frustrated by the essential nonlinear features in the hydrodynamic case. Even in the case of EM waves in

Near-field acoustic streaming jet.

A numerical and experimental investigation of the acoustic streaming flow in the near field of a circular plane ultrasonic transducer in water is performed, validating the numerical approach and justifying the planar wave assumption in conditions where it is a priori far from obvious.

Modeling fast acoustic streaming: Steady-state and transient flow solutions.

Traditionally, acoustic streaming is assumed to be a steady-state, relatively slow fluid response to passing acoustic waves. This assumption, the so-called slow streaming assumption, was made over a

Time evolution of acoustic streaming from a planar ultrasound source

Eckart‐type acoustic streaming induced in confined sound beams from a piston source is examined in water theoretically and experimentally. Axisymmetric flow equations with a spatially distributed

Velocity of Mass Transport to Model Acoustic Streaming: Numerical Application to Annular Resonators

The acoustic wave propagation in thermo-viscous fluid can generate slow phenomena such as acoustic streaming, by non-linear processes that are mainly confined in the acoustical boundary layers.

Acoustic Streaming due to Attenuated Plane Waves

Theories for calculating steady streaming associated with sound fields are reviewed, comparing the methods and approximations of various authors. Two illustrative problems are worked out, both for

Etude expérimentale et théorique d'un écoulement entraîné par des ultrasons (acoustic streaming)

Acoustic streaming, i.e. the steady flow induced by a propagating acoustic wave, is investigated here with both experimental and numerical approaches. The ultrasound source is a 2MHz transducer with

The mechanism of generation of acoustic streaming

Acoustic streaming is a stationary fluid motion induced by intense ultrasound. This paper describes the mechanism of generation of acoustic streaming, theoretically and experimentally. A qualitative

Stability of buoyant convection in a layer submitted to acoustic streaming.

The linear stability of the flows induced in a fluid layer by buoyant convection and by acoustic streaming is studied, and insight into the stabilizing and destabilizing mechanisms is gained from the analysis of the fluctuating energy budget associated with the disturbances at threshold.

Instabilities in the Rayleigh-Bénard-Eckart problem.

Energy analyses of the instabilities at threshold have indicated that the change of the thresholds can be connected to the modifications induced by the streaming flow on the critical perturbations.
