Numerical computation methods are used more and more as tools for solving hydraulic and
environmental engineering problems, and as turbulence mostly plays an important role in …

A finite-volume formulation is presented that solves the three-dimensional, nonhydrostatic
Navier–Stokes equations with the Boussinesq approximation on an unstructured, staggered …

A free surface may be deformed by fluid motions; such deformation may lead to surface
roughness, breakup, or disintegration. This paper describes the wide range of free-surface …

Computational fluid dynamics, commonly known by the acronym 'CFD', continues to have
significant expansion. There are many software packages available that solve fluid flow …

A three‐dimensional numerical model based on the full Navier–Stokes equations (NSE) in σ‐
coordinate is developed in this study. The σ‐coordinate transformation is first introduced to …

We develop an efficient and versatile numerical model for carrying out high-resolution
simulations of turbulent flows in natural meandering streams with arbitrarily complex …

A large-eddy simulation has been performed to study the detailed sediment dynamics that
occur in channel flow over ripples. The code solves the Navier-Stokes equations and an …

Modelling large-scale wave fields and their interaction with coastal and offshore structures
has become much more feasible over the last two decades with increases in computer …

Two-and three-dimensional numerical simulations are performed to study interfacial waves
in a periodic domain by imposing a source term in the horizontal momentum equation …

We develop a three‐dimensional numerical model to simulate bed form dynamics in a
turbulent boundary layer. In the numerical model, hydrodynamics is solved in a moving …
