An equation for waves in a fluid moving with rotating helical motion along the axis of rotation

José Marín Antuña

Abstract


For possible applications in the theoretical study of wave processes in different kind of devices of important technical applications, and also from the pure physical and mathematical point of view, we develop a model to describe small acoustic oscillations in a rotating fluid with a helicoidal movement along the rotating axis. A non classical fourth order partial differential equation is obtained to describe such movements. We study some particular cases and compare this cases with equations obtained in previous papers.

Keywords


Rotating fluid; helicoidal movement; rotating axis; acoustic oscillations
