In this paper, the author analyzes post-bore noise problem in mixed pipe-flow modeling, which uses shock-capturing methods within single-equation frameworks. The study reveals that origin of these numerical noises following pipe-filling is sudden jump from free-surface gravity wave speed c to a significantly higher constant pipe acoustic ac during surcharging. This abrupt transition results an excessively large Laplacian type dissipation, overwhelms physical fluxes, reverses their...
Abstract One of major difficulties in the implementation meshless methods is imposition essential boundary conditions as approximations do not pass through nodal parameter values. As a consequence, quite awkward. In this paper, displacement constraint equations method (DCEM) proposed for conditions, which treated to discrete obtained from Galerkin methods. Instead using Lagrange multipliers and penalty method, procedure unknowns are partitioned into two subvectors, one consisting on Γ u ,...
The Fourier analysis and applications of Weighted Compact Fifth-order Nonlinear Scheme, which is called as WCNS-E-5, are presented in this paper. Using weighted technique, the nonlinear adaptive solver automatically chooses locally smoothest stencil, hence avoiding crossing discontinuities interpolations at cell-edges much possible. As one high-order WCNS developed before, WCNS-E-5 fifth-order accuracy smooth region third-order vicinity discontinuities. By features discussed terms...
This paper presents a coupled two-dimensional model that can produce more stable numerical simulation of rapid bed evolution than the conventional decoupled model. To solve bed-load sediment transport terms using Godunov-type central-upwind method, novel scheme to estimate fluxes which accurate results previously reported is proposed pair local wave speeds different from those used for flow. The shallow water equations are flow velocities and depth. level solved by an Exner-based equation...
We develop a new moving-water equilibria preserving numerical scheme for the Saint-Venant system. The is designed in two major steps. First, geometric source term incorporated into discharge flux, which results hyperbolic system with global flux. Second, equation relaxed so that nonlinearity moved stiff right-hand side of added auxiliary equation. main advantages are (i) no special treatment required, and (ii) nonlinear (cubic) equations should be solved to obtain point values water depth...
In this study, we propose a novel modified pipe hydrodynamic model with partial relaxation approach and develop corresponding numerical algorithm within the framework of finite volume method for its computation to enable robust, accurate, comprehensive modeling. The proposed provides some key improvements compared existing schemes simulating mixed flows: (1) it is capable preserving both moving- stationary-water steady states, (2) effectively reduces post-bore oscillations while maintaining...
T HE typical theory for the finite difference method is that partial equations (PDEs) are discretized in space using a Taylor series expansion and solving it variables at discrete points. The derivatives written as functions of on neighboring approximations said to be high-order accurate when power p leading truncate error O h greater than two. Because advantages high-flow structure resolution nice discontinuity capturing precision, schemes playing important roles computational fluid...
Clean technology has become a key feature due to increasing environmental concerns. Swirling flows, being directly associated with combustion performance and hence minimized pollutant formation, are encountered in most propulsion power-generation devices. In this study, the development process of conceptual swirl burner developed at Swedish National Centre for Combustion Technology (CeCOST), is presented. Utilizing extensive computational fluid dynamics (CFD) analysis, both lead time cost...
