|Title:||Evolution of turbulence in an oscillatory flow in a smooth-walled channel: A viscous secondary instability mechanism||Contributor(s):||Cosgrove, J (author); Buick, J (author); Tonge, S (author)||Publication Date:||2003||DOI:||10.1103/PhysRevE.68.026302||Handle Link:||https://hdl.handle.net/1959.11/209||Abstract:||In this paper, a comparison is made of the evolution of turbulence in oscillatory channel flows with a zero-mean velocity in two and three dimensions, using the numerical technique of the lattice Boltzmannmethod. The results confirm a primary two-dimensional instability. Evidence is shown of a secondary, viscous three-dimensional instability mechanism acting in the oscillatory boundary layer, which is consistent with experimental observations.||Publication Type:||Journal Article||Source of Publication:||Physical Review E: covering statistical, nonlinear, biological, and soft matter physics, 68(2), p. 026302-1-026302-5||Publisher:||American Physical Society||Place of Publication:||College Park, USA||ISSN:||1539-3755||Field of Research (FOR):||020303 Fluid Physics||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Statistics to Oct 2018:||Visitors: 123
