IMEX_SfloW2D 1.0: a depth-averaged numerical flow model for pyroclastic avalanches

a 2d numerical depth-averaged model for unsteady flow in open channel bends

the purpose of this paper is to present a 2d depth-averaged model for simulating and examining unsteady flow patterns in open channel bends. in particular, this paper proposes a 2d depth-averaged model that takes into account the influence of the secondary flow phenomenon through calculation of the dispersion stresses. the dispersion terms which arose from the integration of the product of the ...

A Numerical Study of Flow Dispersion Stresses in 2D Depth Averaged Model for Curvilinear Flow Domain

The objective of the study is to present a two dimensional model with incorporated dispersion terms as source term in transport equations for simulation of curvilinear flow field. The comparison of the simulated velocity field and water surface elevation indicated that the incorporation of such terms has reasonably improved the secondary flow scenario. Keywords— Flow simulation, numerical model...

Numerical Modeling of the Depth-Averaged Flow Over a Hill

This paper reports the development and application of a 2D depth-averaged model. The main goal of this contribution is to apply the depth averaged equations to a wind park model in which the treatment of the geometry, introduced on the mathematical model by the mass and momentum source terms. The depth-averaged model will be used in future to find the optimal position of wind turbines in the wi...

A depth-averaged electrokinetic flow model for shallow microchannels

Electrokinetic flows with heterogeneous conductivity configuration occur widely in microfluidic applications such as sample stacking and multidimensional assays. Electromechanical coupling in these flows may lead to complex flow phenomena, such as sample dispersion due to electro-osmotic velocity mismatch, and electrokinetic instability (EKI). In this work we develop a generalized electrokineti...
