چکیده
This paper presents a method for modelling interfacial mass transfer in Interface Capturing simulations of two-phase flow with phase change. The model enables mechanistic prediction the local rate change at vapour-liquid interface on arbitrary computational meshes and is applicable to realistic cases involving mixtures large density ratios. simulation methodology based Volume Of Fluid (VOF) representation flow, whereby an region which occurs implicitly identified by indicator, this case volume fraction liquid, varies from value pertaining "bulk" liquid bulk vapour. novel proposed here has been implemented using Finite framework solution methods typical "industrial" CFD practice. capturing without need introduce elaborate but artificial smearing term as often done other techniques. validated via comparison analytical solutions planar evaporation bubble growth test cases, against experimental observations steam growth.

A mimetic tensor artificial viscosity method for arbitrary polyhedral meshes
We construct a new mimetic tensor artificial viscosity on general polyhedral meshes. The tensor viscosity is designed as a discretization of the differential operator div (μ∇u) with the full fourth-order tensor μ. We demonstrate performance of the new artificial viscosity on a set of test problems.
متن کاملArbitrary order BEM-based Finite Element Method on polygonal meshes
Polygonal meshes show up in more and more applications and the BEMbased Finite Element Method turned out to be a forward-looking approach. The method uses implicitly defined trial functions, which are treated locally by means of Boundary Element Methods (BEM). Due to this choice the BEM-based FEM is applicable on a variety of meshes including hanging nodes. The aim of this presentation is to gi...
متن کاملIntegral relations, a simplified method to find interfacial resistivities for heat and mass transfer
Integral relations were used to predict interface film transfer coefficients for evaporation and condensation. According to these, all coefficients can be calculated for one-component systems, using the thermal resistivity and the enthalpy profile through the interface. The expressions were verified in earlier work using non-equilibrium molecular dynamics simulations for argon-like particles, w...
متن کاملSimulating Drilling on Tetrahedral Meshes
Bone drilling is a fundamental task in several surgical procedures, including mastoidectomy, cochlear implantation, orbital surgery. It consists in eroding the part of the bone in contact with the tip of the surgical tool when a sufficient pressure is exerted. Since the bone is an almost rigid material, the bone drilling simulations usually employ voxel-based representations of the bone, so tha...
متن کاملA Uniformly Convergent Method on Arbitrary Meshes for a Semilinear Convection-diffusion Problem with Discontinuous Data
This paper deals with a uniform (in a perturbation parameter) convergent difference scheme for solving a nonlinear singularly perturbed twopoint boundary value problem with discontinuous data of a convection-diffusion type. Construction of the difference scheme is based on locally exact schemes or on local Green’s functions. Uniform convergence with first order of the proposed difference scheme...
