DOI: 10.1007/s11012-020-01185-3
Abstract: The occurrence of slip complicates the estimation of the viscosity in rheometric flows. Thus, special analyses and experimental protocols are needed in order to obtain reliable estimates of the viscosity and other rheological parameters. In… read more here.

DOI: 10.1017/jfm.2018.971
Abstract: The onset of transient turbulence in minimal plane Couette flow has been identified theoretically as homoclinic tangency with respect to a simple edge state for the Navier–Stokes equation, i.e., the gentle periodic orbit (the lower… read more here.

DOI: 10.1017/jfm.2019.377
Abstract: The linear stability of plane Couette flow is investigated when the plates are horizontal, and the fluid is stably stratified with a cubic basic density profile. The disturbances are treated as inviscid and diffusion of… read more here.

DOI: 10.1017/jfm.2020.718
Abstract: Abstract Rayleigh–Bénard convection (RBC) and Taylor–Couette flow (TCF) are two paradigmatic fluid dynamical systems frequently discussed together because of their many similarities despite their different geometries and forcing. Often these analogies require approximations, but in… read more here.

DOI: 10.1017/jfm.2021.45
Abstract: Abstract We present a derivation that begins with the Navier–Stokes equation and ends with a prediction of multiple statistically stable states identical to those observed in a spanwise rotating plane Couette flow. This derivation is… read more here.
