A non-linear ®lter for one- and two-dimensional open channel ̄ows with shocks
نویسندگان
چکیده
Modeling ̄ows with shocks creates numerical challenges due to the oscillations in the vicinity of the discontinuity. This paper presents the advantage of using a non-linear ®lter for obtaining oscillatory free solution for oneand two-dimensional open channel ̄ows. Numerical results are compared with those of other conventional high-resolution schemes to demonstrate the accuracy of the solution. As discussed in the course of this document, the present formulation is computationally faster, and simpler to code while maintaining consistent results with the standard schemes.

Analytical Solutions for Spatially Variable Transport-Dispersion of Non-Conservative Pollutants
Analytical solutions have been obtained for both conservative and non-conservative forms of one-dimensional transport and transport-dispersion equations applicable for pollution as a result of a non-conservative pollutant-disposal in an open channel with linear spatially varying transport velocity and nonlinear spatially varying dispersion coefficient on account of a steady unpolluted lateral i...
متن کاملA multiple grid algorithm for one-dimensional transient open channel ̄ows
Numerical modeling of open channel ̄ows with shocks using explicit ®nite dierence schemes is constrained by the choice of time step, which is limited by the CFL stability criteria. To overcome this limitation, in this work we introduce the application of a multiple grid algorithm to the ®eld of computational hydraulics. By coupling this algorithm to a second-order accurate MacCormack scheme, w...
متن کاملDetermination of Thermal Resistance in Three-Dimensional Analysis of Micro-Channel Heat Sink with Non - Newtonian Fluids
Micro-Channel Heat Sink is a heat exchanger which is used to control the temperature of electronic devices with high heat flux. A comprehensive thermal model for the micro-channels should include three dimensional conduction analysis in the solid body together with three dimensional developing fluid flow as well as heat transfer analyses in the fluid section. This paper reports on a research ...

متن کاملNumerical solution of the one dimensional non-linear Burgers equation using the Adomian decomposition method and the comparison between the modified Local Crank-Nicolson method and the VIM exact solution
The Burgers’ equation is a simplified form of the Navier-Stokes equations that very well represents their non-linear features. In this paper, numerical methods of the Adomian decomposition and the Modified Crank – Nicholson, used for solving the one-dimensional Burgers’ equation, have been compared. These numerical methods have also been compared with the analytical method. In contrast to...
