Numerical Modeling of Saline Gravity Currents Using EARSM and Buoyant k- Turbulence Closures
Gravity currents are very common in nature and may appear in rivers, lakes, oceans, and the atmosphere. They are produced by the buoyant forces interacting between fluids of different densities and may introduce sediments and pollutants into water bodies. In this study, the hydrodynamics and propagation of gravity currents are investigated using WISE (Width Integrated Stratified Environments), ...
متن کاملTwo- and three-dimensional Direct Numerical Simulation of particle-laden gravity currents
In this numerical study, we are interested in the prediction of a mono-disperse dilute suspension particle-laden flow in the typical lock-exchange configuration. The main originality of this work is that the deposition of particles is taken into account for high Reynolds numbers up to 10 000, similar to the experimental ones. Unprecedented twoand three-dimensional Direct Numerical Simulations (...
متن کاملNumerical Modelling of Two-dimensional and Axisymmetric Gravity Currents
A series of two-dimensional, axisymmetric and three-dimensional numerical flow simulations using an Implicit Large Eddy Simulation (ILES) are carried out for gravity-driven fluid flows, the results are compared directly with experiments undertaken to test the model. Two-dimensional results show that the Large Eddy algorithm is successful in modelling a gravity current’s large scale structure. E...
متن کاملThree-Dimensional Simulation of Qeshm Channel Currents
Qeshm Channel is a shallow and narrow waterway located between Qeshm Island and the mainland in the vicinity of Hormuzgan Province, Islamic Republic of Iran. This channel is important because of its economic, industrial, fisheries and navigation role it plays as well as environmental issues it presents in the region. A prognostic study was performed to simulate currents in this channel, using C...
متن کاملNumerical simulation of a collapsing bubble subject to gravity
The present paper focuses on the simulation of the expansion and aspherical collapse of a laser-generated bubble subjected to an acceleration field and comparison of the results with instances from high-speed videos. The interaction of the liquid and gas is handled with the Volume Of Fluid (VOF) method. Compressibility effects have been included for each phase to predict the propagation of pres...
