Massive computations of three-dimensional (3D) flow in subcritical flow state are carried out
to investigate the transition from 3D steady flow to time-periodic oscillatory flow via Hopf …

We theoretically and experimentally investigate the mechanism underlying the generation of
upstream-propagating waves induced by a steady current over a horizontal bottom with a …

In this paper, we show that Stokes drift may be significantly affected when an incident
intermediate or shallow water surface wave travels over a corrugated sea floor. The …

Investigating the wave hydrodynamics of free-surface flow over rippled bottoms is a
continuing concern due to the existence of submarine multiple sandbars and ambient flow in …

In a linearly stratified fluid, two sets of resonant triads with one member in common, hence
coupled, can arise for a wide range of wave numbers where all five waves travel in the same …

The transition from steady-state flow to periodic oscillatory flow for the natural convection by
Hopf bifurcation is investigated in a three-dimensional (3D) cavity. The spectral collocation …

The wave–current–seabed interaction problem is studied by using a coupled-mode system
developed for modeling wave scattering by non-homogeneous, sheared currents in variable …

We show that in free surface flows, a uniform, streamwise current over small-amplitude wavy
bottom topography generates cross-stream drift velocity. This drift mechanism, referred to as …

Here we propose a minimal analog gravity setup and suggest how to select two surface
gravity wave packets in order to mimic some key aspects of Hawking radiation from the …

The flow and heat transfer characteristics of a three-dimensional cavity filled with a
conducting fluid are investigated in this study. The three-dimensional Navier-Stokes …
