Physical Modeling of Vanishing Bores in Open-Channel Flows
نویسندگان
چکیده
When an undular bore is propagating upstream against a subcritical flow in flat channel, its leading front may weaken and vanish. The present study physically investigated the whole decaying process of vanishing bores relatively large facility. invert was made mobile or fixed natural river gravels. Detailed sampling water surface elevations velocities performed combination with high-resolution photo video recordings. Despite some increased turbulence characteristics linked to arrival, no sediment motion observed underneath bores. quantitative results provide unique benchmark data set for further later-stage propagations.

Assessment of Turbulent Models in Computation of Strongly Curved Open Channel Flows
Several rigorous turbulent models have been developed in the past years and it can be seen that more research is needed to reach a better understanding of their generality and precision by verifying their applications for distinct hydraulic phenomena; under certain assumptions. This survey evaluates the performance of Standard k-ε, Realizable k-ε, RNG k-ε, k-ω and RSM models in predicting flow ...
متن کاملGradually-varied Flows in Open-channel Networks
− Reported here are some results obtained, from a calculus algorithm application that, based on known equation analytical solutions of water flow profiles, allows the study of steady-state, gradually varied flow in open channel networks. The procedure allows to calculate, in the case of slow water flow into gradually downward slope channels, in the direction of motion, the florates and water le...
متن کاملPort-Hamiltonian discretization for open channel flows
A finite-dimensional Port-Hamiltonian formulation for the dynamics of smooth open channel flows is presented. A numerical scheme based on this formulation is developed for both the linear and nonlinear shallow water equations. The scheme is verified against exact solutions and has the advantage of conservation of mass and energy to the discrete level.
متن کاملModeling of Micro/nano Channel Flows
This paper reviews the models for the fluid flow in micro/nano channels developed previously. These models include the full MDS (molecular dynamics simulation) model, the quasi-continuum model, the modified Navier-Stokes equation model, the dissipative particle dynamics method, the lattice Boltzman method, the multiscale hybrid model and the flow factor approach model. It was pointed out that m...
متن کاملAcross-channel distribution of the mean and tidal flows in the Khuran Channel, Persian Gulf, Iran
The Khuran Channel, Southern Iran (26°45’N), is a topographically complex channel which is open at both ends. Owning to its particular geometry, this narrow channel is subjected to strong tidal currents.Across-channel distribution of the mean and tidal flows were obtained over a semidiurnal tidal cycle in the Khuran Channel where the highest tidal velocity in the third day of the seco...
