Stability of acoustic streaming jets
Bjarne Vincent, Abhishek Kumar, Daniel Henry +3
We study the stability of a steady Eckart streaming jet that is acoustically forced at one end of a closed cylindrical cavity and impinges the wall at the other end, where a recirc…

Phenomenology of laminar acoustic streaming jets
Bjarne Vincent, Daniel Henry, Abhishek Kumar +3
This work identifies the physical mechanisms at play in the different flow regions along an Eckart acoustic streaming jet by means of numerical simulation based on a novel modeling…

Suppressing instabilities in mixed baroclinic flow using an actuation based on receptivity
Abhishek Kumar, Alban Pothérat
This paper presents a method to stabilise oscillations occurring in a mixed convective flow in a nearly hemispherical cavity, using actuation based on the receptivity map of the un…
