Non-normal weakly nonlinear analysis: asymptotic consistency and non-universality
Matthew McCormack, Gregory P. Chini, Rich R. Kerswell
Non-normality can induce large transient growth in linearly stable systems. Determining whether this growth triggers a transition in the underlying nonlinear system, however, requi…

Aspect-ratio-dependent heat transport by baroclinic acoustic streaming
Jacques Abdul Massih, Remil Mushthaq, Guillaume Michel +1
Standing acoustic waves have been known to generate Eulerian time-mean 'streaming' flows at least since the seminal investigation of Lord Rayleigh in the 1880s. Nevertheless, a rec…
