Turbulent Mixing and Dissipation Around Rough Seamounts
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Seamounts are critical components of the global ocean energy budget, contributing significantly to turbulent dissipation through their interaction with large‐scale flows. However, most previous numerical investigations used smoothed bathymetry that omits small‐scale topographic variability. We use turbulence‐resolving large‐eddy simulations to

QUANTITATIVE STUDIES ABOUT TSUNAMI GENERATION AND PROPAGATION WAVES BY A STOCHASTIC SUBMARINE SLUMP AND LANDSLIDE SOURCE MODEL [PDF]
Science of Tsunami Hazards, 2018 Tsunami generation and propagation due to a vertical time-dependent extent of a stochastic submarine slump and landslide model for different values of Froude number and noise intensity are investigated.

Efficient computation of two-dimensional steady free-surface flows
, 2017 We consider a family of steady free-surface flow problems in two dimensions, concentrating on the effect of nonlinearity on the train of gravity waves that appear downstream of a disturbance.

On the Biases of Empirical Riverine Gas Transfer Velocity Models at High Submergence
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Quantifying gas transfer velocity in rivers, a key step in characterizing riverine ecosystems, carbon cycling, and greenhouse gas emissions, typically relies on empirical or semi‐empirical models. Although fluid mechanics theory predicts a direct influence of the depth‐to‐bed‐roughness‐size ratio (relative submergence) on gas transfer velocity,

Godunov type scheme for the linear wave equation with Coriolis source term
ESAIM: Proceedings and Surveys, 2017 We propose a method to explain the behaviour of the Godunov finite volume scheme applied to the linear wave equation with Coriolis source term at low Froude number. In particular, we use the Hodge decomposition and we study the properties of the modified

Investigation of the Bulbous Bow Effect on the Resistance of a Container Ship by CFD Method
نشریه مهندسی دریا, 2021 In commercial ships, wave making resistance is a part of total resistance which to reduce it, a bulbous bow is added to the ship bow. To investigate the effect of bulbous bow on total resistance, a container ship model is simulated with and without the ...

Flow in a waterfall with large Froude number
Journal of Computational and Applied Mathematics, 1994 An approximate method is developed to solve the full nonlinear equations governing two-dimensional irrotational flow in the free waterfall, falling under the influence of gravity, at high Froude number based on conditions far upstream. Schwarz-Christoffel transformation is used to map the region, in the complex potential-plane, onto the upper half ...

Finite Froude and Rossby number baroclinic vortex pairs
Geophysical & Astrophysical Fluid DynamicsWe study the evolution of baroclinically-unstable pairs of opposite-signed vortices in a three-dimensional, continuously-stratified, rotating fluid at finite Froude and Rossby numbers. We explore how ageostophic motions affect the evolution of the vortex pairs, in particular the dynamical asymmetry these motions induce in their evolution.
