Onset of centrifugal instability at a rotating cylinder in a stratified fluid

JB Flór, L Hirschberg, BH Oostenrijk, GJF van Heijst - Physics of Fluids, 2018 - pubs.aip.org
In this experimental note, we consider the centrifugal instability of a laminar shear layer,
generated by the impulsive start of the rotation of a circular solid cylinder about its vertical …

Second-order approximation to forced oscillations of thermal convection under small time-varying forcing

H Ishida, S Sugimura, T Kuroda, G Kawahara - International Journal of Heat …, 2016 - Elsevier
This study presents a theory that approximates steady forced oscillations up to the second-
order with respect to vibration amplitude a. This is the extension of the first-order …
