Flapping instability of elastic disks in Stokes flows
Yijiang Yu, Hugo Perrin, Michael D. Graham +1
Fluid-structure interactions at low Reynolds number can lead to a much richer phenomenology than previously expected. Here, we study the dynamics of a freely suspended, thin elasti…
Structures of elastoinertial turbulence in pipe flow
Manish Kumar, Michael D. Graham
Elastoinertial turbulence (EIT) is a self-sustaining chaotic state resulting from the interplay between inertia and elasticity in the flow of dilute polymeric solutions, and its em…
Identifying efficient routes to laminarization: an optimization approach
Jake Buzhardt, Michael D. Graham
The nonlinear and chaotic nature of turbulent flows poses a major challenge for designing effective control strategies to maintain or induce low-drag laminar states. Traditional li…
Flow instabilities in circular Couette flow of wormlike micelle solutions with a reentrant flow curve
Richard J. Hommel, Michael D. Graham
In this work, we numerically investigate flow instabilities of inertialess circular Couette flow of dilute wormlike micelle solutions. Using the reformulated reactive rod model (RR…
