Solitary Wave Solution of Flat Surface Internal Geophysical Waves with Vorticity [PDF]
, 2017 A fluid system bounded by a flat bottom and a flat surface with an internal wave and depth-dependent current is considered. The Hamiltonian of the system is presented and the dynamics of the system are discussed. A long-wave regime is then considered and

Hamiltonian model for coupled surface and internal waves in the presence of currents [PDF]
, 2017 We examine a two dimensional fluid system consisting of a lower medium bounded underneath by a flatbed and an upper medium with a free surface. The two media are separated by a free common interface.

Swimming of a uniform deformable sphere in a viscous incompressible fluid with inertia
, 2020 The swimming of a deformable uniform sphere is studied in second order perturbation theory in the amplitude of the stroke. The effect of the first order reaction force on the first order center of mass velocity is calculated in linear response theory by ...

Hamiltonian models for the propagation of irrotational surface gravity waves over a variable bottom [PDF]
, 2017 A single incompressible, inviscid, irrotational fluid medium bounded by a free surface and varying bottom is considered. The Hamiltonian of the system is expressed in terms of the so-called Dirichlet-Neumann operators. The equations for the surface waves

Extended Self Similarity works for the Burgers equation and why [PDF]
, 2009 Extended Self-Similarity (ESS), a procedure that remarkably extends the range of scaling for structure functions in Navier--Stokes turbulence and thus allows improved determination of intermittency exponents, has never been fully explained.

Phase-space Lagrangian dynamics of incompressible thermofluids
, 2009 Phase-space Lagrangian dynamics in ideal fluids (i.e, continua) is usually related to the so-called {\it ideal tracer particles}. The latter, which can in principle be permitted to have arbitrary initial velocities, are understood as particles of ...

Lagrangian Refined Kolmogorov Similarity Hypothesis for Gradient Time-evolution in Turbulent Flows
, 2009 We study the time evolution of velocity and pressure gradients in isotropic turbulence, by quantifying their decorrelation time scales as one follows fluid particles in the flow.

The small-scale dynamo: Breaking universality at high Mach numbers
, 2013 (Abridged) The small-scale dynamo may play a substantial role in magnetizing the Universe under a large range of conditions, including subsonic turbulence at low Mach numbers, highly supersonic turbulence at high Mach numbers and a large range of ...
