...S. B. Naveen Kumar; I. S. Shivakumara; B. M. Shankar In this paper, the effect of Coriolis force is explored on convective instability of a doubly diffusive incompressible couple stress fluid layer with gravity acting downward. A linear stability analysis is used to obtain the conditions...

... these functions are multivalued, but the lowest branch is the only physically important one, as it defines the upper bound for the linear stability and, hence, the onset condition for the linear instability. When we refer to the neutral stability function R ( a ) and the dispersion relation ω...

...A. Barletta; M. Celli; A. V. Kuznetsov The linear stability of a parallel flow in a heterogeneous porous channel is analyzed by means of the Darcy law and the Oberbeck–Boussinesq approximation. The basic velocity and temperature distributions are influenced by the effect of the viscous dissipation...

... a nonlinear temperature profile within the layer. The linear stability of this nonisothermal base flow is then investigated with respect to the onset of convective rolls. The third kind boundary condition on the bottom boundary plane may imply adiabatic/isothermal conditions on this plane when the Biot number...

...Manosh C. Paul; D. Andrew S. Rees Numerical simulations are performed to investigate the linear stability of a two-dimensional incompressible free convection flow induced by a vertical semi-infinite heated flat plate. A small-amplitude local temperature disturbance with a slowly increasing...
