Global linear and nonlinear bifurcation analysis is used to revisit the spiral vortex breakdown
of nominally axisymmetric swirling jets. For the parameters considered herein, stability …

A number of two-dimensional time-periodic flows, for example the Kármán street wake of a
symmetrical bluff body such as a circular cylinder, possess a spatio-temporal symmetry: a …

Turing–Hopf instabilities for reaction-diffusion systems provide spatially inhomogeneous
time-periodic patterns of chemical concentrations. In this paper we suggest a way for …

The shear layer instability in the flow between two counter-rotating disks enclosed by a
cylinder is investigated experimentally and numerically, for radius-to-height ratio between 2 …

The classical theory of electromagnetism is entirely revised in this book by proposing a
variant of Maxwell equations that allows solitonic solutions (photons). The Lagrangian is the …

The swirl flow minichannel heat sink has shown to be a promising alternative for thermal
management of high heat flux applications, such as electronics and concentrated …

Using a combination of critical point theory of ordinary differential equations and numerical
simulation for the three-dimensional unsteady Navier–Stokes equations, we study possible …

The bifurcations and the nonlinear dynamics of the von Kármán swirling flow between
exactly counterrotating disks in a stationary cylinder are experimentally investigated by …

The flow in an enclosed completely filled rapidly rotating cylinder that is driven by the
differential corotation of the top lid is studied numerically. Although the flow is in a very …

In this paper we study the spatiotemporal properties of waves in the Lorenz-96 model and
their dependence on the dimension parameter n and the forcing parameter F. For F> 0 the …
