چکیده
Abstract. This paper discusses numerical simulation techniques using a moving mesh approach together with the multigrid fictitious boundary method (FBM) for liquid-solid flow configurations. The flow is computed by an ALE formulation with a multigrid finite element solver (FEATFLOW), and the solid particles are allowed to move freely through the computational mesh which can be adaptively aligned by the moving mesh method based on an arbitrary grid. Numerical results show that the presented method can accurately and efficiently handle prototypical particulate flow situations.

Fictitious boundary and moving mesh methods for the numerical simulation of rigid particulate flows
In this paper, we investigate the numerical simulation of rigid particulate flows using a new moving mesh method combined with the multigrid fictitious boundary method (FBM) [9, 10]. With this approach, the mesh is dynamically relocated through a special partial differential equation to capture the region near the surface of the moving particles with high accuracy. The complete system is realiz...

متن کاملNumerical Simulation of Flow Past Oscillating Airfoil Using Oscillation of Flow Boundary Condition
The present study is devoted to an approximate modeling for numerical simulation of flows past oscillating airfoils. In this study, it is shown that the harmonic oscillating objects can be studied by simple numerical codes that are not able to solve moving grids. Instead of using moving grid for the simulation of flowfield around an oscillating airfoil, this unsteady flow is solved on a fixed g...
متن کاملNumerical Methods to Simulate Turbulent Dispersed Flows in Complex Geometries
Population Balance is a prominent ingredient of modeling transport phenomena. Population Balance Equations (PBEs) are coupled to Computational Fluid Dynamics (CFD) to simulate turbulent dispersed flows. One of the arising challenges is to obtain an appropriate discretization technique for the internal coordinate of PBEs, so the resulting equations can lead to acceptable solutions with affordabl...
متن کاملSimulation of Pitching and Heaving Airfoil with Oscillation of Flow Boundary Condition
A pressure based implicit procedure to solve the Euler and Navier-Stokes equation is developed to predict transonic viscous and inviscid flows around the pitching and heaving airfoils with a high reslution scheme. In this process, nonorthogonal and non moving mesh with collocated finite volume formulation are used. In order to simulate pitching or heaving airfoil, oscillation of flow boundary c...
