Linear and Secondary Instabilities in Incompressible Axisymmetric Boundary Layers: Effect of Transverse Curvature
N. Vinod, Rama Govindarajan
The incompressible boundary layer in the axial flow past a cylinder has been shown Tutty et. al.(\cite{tutty}) to be stabler than a two-dimensional boundary layer, with the helical…
Gravity-free hydraulic jumps and metal femtocups
Rama Govindarajan, Manikandan Mathur, Ratul DasGupta +3
Hydraulic jumps created by gravity are seen every day in the kitchen sink. We show that at small scales a circular hydraulic jump can be created in the absence of gravity, by surfa…
The critical Reynolds number of a laminar mixing layer
Pinaki Bhattacharya, M. P. Manoharan, Rama Govindarajan +1
It has hitherto been widely considered that a mixing layer is unstable at all Reynolds numbers. However this is untenable from energy considerations, which demand that there must e…
The effect of wall heating on instability of channel flow
A. Sameen, Rama Govindarajan
A comprehensive study of the effect of wall heating or cooling on the linear, transient and secondary growth of instability in channel flow is conducted. The effect of viscosity st…
