Tollmien-Schlichting route to elastoinertial turbulence in channel flow
Ashwin Shekar, Ryan M. McMullen, Beverley J. McKeon +1
Direct simulations of two-dimensional channel flow of a viscoelastic fluid have revealed the existence of a family of Tollmien-Schlichting (TS) attractors that is nonlinearly self-…
Interaction of forced Orr-Sommerfeld and Squire modes in a low-order representation of turbulent channel flow
Ryan M. McMullen, Kevin Rosenberg, Beverley J. McKeon
A resolvent-based reduced-order representation is used to capture time-averaged second-order statistics in turbulent channel flow. The recently-proposed decomposition of the resolv…
Self-sustained elastoinertial Tollmien-Schlichting waves
Ashwin Shekar, Ryan M. McMullen, Beverley J. McKeon +1
Direct simulations of two-dimensional plane channel flow of a viscoelastic fluid at Reynolds number Re = 3000 reveal the existence of a family of attractors whose structure closely…
Critical-layer structures and mechanisms in elastoinertial turbulence
Ashwin Shekar, Ryan M. McMullen, Sung-Ning Wang +2
Simulations of elastoinertial turbulence (EIT) of a polymer solution at low Reynolds number are shown to display localized polymer stretch fluctuations. These are very similar to s…
