• Investigation of the Transitions to Turbulence Employing Simple Siphons

  Oral-In-person

  Publication: Prior to the APS Global Summit in Denver, we intend to submit a letter to PRL reporting on our key finding, that being, that localized mode 1 entrance generated turbulence disturbances transition to mode 2 (ubiquitous) turbulence when the washdown velocity of a mode 1 disturbance exceeds twice the average flow velocity.
