Koopman mode expansions between simple invariant solutions
Jacob Page, Rich R. Kerswell
A Koopman decomposition is a powerful method of analysis for fluid flows leading to an apparently linear description of nonlinear dynamics in which the flow is expressed as a super…
Thermodynamics of the scalar radiation in the presence of a reflecting plane wall
E. S. Moreira
This paper investigates further how the presence of a single reflecting plane wall modifies the usual Planckian forms in the thermodynamics of the massless scalar radiation in -…
Stabilisation and drag reduction of pipe flows by flattening the base profile
E. Marensi, A. P. Willis, R. R. Kerswell
Recent experimental observations (Kuehnen et al., 2018) have shown that flattening a turbulent streamwise velocity profile in pipe flow destabilises the turbulence so that the flow…
Connection between Nonlinear Energy Optimization and Instantons
Daniel Lecoanet, Rich R. Kerswell
How systems transit between different stable states under external perturbation is an important practical issue. We discuss here how a recently-developed energy optimization method…
