New observations in transient hydrodynamic perturbations. Frequency jumps, intermediate term and spot formation
Stefania Scarsoglio, Francesca De Santi, Daniela Tordella
Sheared incompressible flows are usually considered non-dispersive media. As a consequence, the frequency evolution in transients has received much less attention than the wave ene…

Kolmogorov scaling bridges linear hydrodynamic stability and turbulence
Stefania Scarsoglio, Francesca De Santi, Daniela Tordella
The way in which kinetic energy is distributed over the multiplicity of inertial (intermediate) scales is a fundamental feature of turbulence. According to Kolmogorov's 1941 theory…
