چکیده
Abstract In this paper we extend the application of unstructured high-order finite-volume central-weighted essentially non-oscillatory (CWENO) schemes to multicomponent flows using interface capturing paradigm. The developed method achieves accurate solution in smooth regions, while providing oscillation free solutions at discontinuous regions. are inherently compact sense that central stencils employed as possible, and directional reduced size, therefore simplifying their implementation. Several parameters influence performance investigated, such reconstruction variables order. is assessed under a series stringent test problems consisting various combinations gases liquids, compared against analytical solutions, computational experimental results available literature. obtained demonstrate robustness new for several applications, well limitations within present interface-capturing

Monotone finite volume schemes for diffusion equations on unstructured triangular and shape-regular polygonal meshes
We consider a nonlinear finite volume (FV) scheme for stationary diffusion equation. We prove that the scheme is monotone, i.e. it preserves positivity of analytical solutions on arbitrary triangular meshes for strongly anisotropic and heterogeneous full tensor coefficients. The scheme is extended to regular star-shaped polygonal meshes and isotropic heterogeneous coefficients.
متن کاملFinite volume Hermite WENO schemes for solving the Hamilton-Jacobi equations II: Unstructured meshes
Abstract. In this paper, we present a new type of Hermite weighted essentially nonoscillatory (HWENO) schemes for solving the Hamilton-Jacobi equations on the finite volume framework. The cell averages of the function and its first one (in one dimension) or two (in two dimensions) derivative values are together evolved via time approaching and used in the reconstructions. And the major advantag...

Finite-volume WENO scheme for viscous compressible multicomponent flows
We develop a shock- and interface-capturing numerical method that is suitable for the simulation of multicomponent flows governed by the compressible Navier-Stokes equations. The numerical method is high-order accurate in smooth regions of the flow, discretely conserves the mass of each component, as well as the total momentum and energy, and is oscillation-free, i.e. it does not introduce spur...
متن کاملA balanced-force control volume finite element method for interfacial flows with surface tension using adaptive anisotropic unstructured meshes
A balanced-force control volume finite element method is presented for three-dimensional interfacial flows with surface tension on adaptive anisotropic unstructured meshes. A new balanced-force algorithm for the continuum surface tension model on unstructured meshes is proposed within an interface capturing framework based on the volume of fluid method, which ensures that the surface tension fo...
