An efficient stabilized finite element scheme for simulating viscoelastic flows Int. J. Numer. Methods Fluids (IF 1.808) Pub Date : 2021-01-17 Yong Chai; Jie Ouyang; Xiaodong Wang
This paper presents an efficient stabilized finite element scheme for solving viscoelastic flow problems at high Weissenberg numbers. The velocity and pressure variables in the momentum balance equations are uncoupled using an incremental fractional step method based on the second order backward differentiation formula (BDF2). The pressure gradient projection (PGP) stabilization technique and the discrete

An immersed boundary method with y+‐adaptive wall function for smooth wall shear Int. J. Numer. Methods Fluids (IF 1.808) Pub Date : 2021-01-17 Yuncheng Xu; Xiaofeng Liu
Immersed boundary (IB) method with a wall function for high Reynolds number flows is attractive when the boundary is complex and evolving. However, when combined with IB method, existing wall functions can not produce smooth wall shear stress, which is important for many processes such as erosion. The root cause is the discontinuity between the log‐law and laminar layers in most wall functions. A wall

A Conforming Discontinuous Galerkin Finite Element Method For The Stokes Problem On Polytopal Meshes Int. J. Numer. Methods Fluids (IF 1.808) Pub Date : 2021-01-16 Xiu Ye; Shangyou Zhang
A new discontinuous Galerkin finite element method for the Stokes equations is developed in the primary velocity‐pressure formulation. This method employs discontinuous polynomials for both velocity and pressure on general polygonal/polyhedral meshes. Most finite element methods with discontinuous approximation have one or more stabilizing terms for velocity and for pressure to guarantee stability

A simplified lattice Boltzmann flux solver for multiphase flows with large density ratio Int. J. Numer. Methods Fluids (IF 1.808) Pub Date : 2021-01-15 Liuming Yang; Chang Shu; Zhen Chen; Yan Wang; Guoxiang Hou
Unlike the conventional multiphase lattice Boltzmann method (LBM), the recently developed finite volume‐based multiphase lattice Boltzmann flux solver (MLBFS) is free from the limitation of the uniform mesh, the coupled time step and mesh spacing, and the high virtual memories. In the MLBFS, the macroscopic equations recovered from the LBM are discretized by the finite volume method while the fluxes

A Meshfree Lagrangian Method for Flow on Manifolds Int. J. Numer. Methods Fluids (IF 1.808) Pub Date : 2021-01-12 Pratik Suchde
In this paper, we present a novel meshfree framework for fluid flow simulations on arbitrarily curved surfaces. First, we introduce a new meshfree Lagrangian framework to model flow on surfaces. Meshfree points or particles, which are used to discretize the domain, move in a Lagrangian sense along the given surface. This is done without discretizing the bulk around the surface, without parametrizing

Simulation of three‐dimensional nonlinear water waves using a pseudospectral volumetric method with an artificial boundary condition Int. J. Numer. Methods Fluids (IF 1.808) Pub Date : 2021-01-11 Mathias Klahn; Per A. Madsen; David R. Fuhrman
This paper presents a pseudospectral method for the simulation of nonlinear water waves described by potential flow theory in three spatial dimensions. The method utilizes an artificial boundary condition that limits the vertical extent of the fluid domain, and it is found that the reduction in domain size offered by the boundary condition enables the solution of the Laplace problem with roughly half

Adaptive Downstream Tensorial Eddy Viscosity for Hybrid LES‐RANS Simulations Int. J. Numer. Methods Fluids (IF 1.808) Pub Date : 2021-01-10 Wanjia Zhang; Tom I.‐P. Shih
An adaptive method is developed to improve the accuracy of eddy‐viscosity RANS model in hybrid LES‐RANS simulations by using available upstream LES results. The method first gets the tensorial eddy viscosity from the upstream LES solution at the LES‐RANS interface and then uses that information to improve the downstream RANS model by invoking the weak‐equilibrium assumption. The proposed method was

A comparison of block preconditioners for isogeometric analysis discretizations of the incompressible Navier‐Stokes equations Int. J. Numer. Methods Fluids (IF 1.808) Pub Date : 2020-12-14 H. Horníková; C. Vuik; J. Egermaier
We deal with numerical solution of the incompressible Navier–Stokes equations discretized using the isogeometric analysis (IgA) approach. Similarly to finite elements, the discretization leads to sparse nonsymmetric saddle‐point linear systems. The IgA discretization basis has several specific properties different from standard FEM basis, most importantly a higher interelement continuity leading to

An ALE‐based finite element strategy for modeling incompressible two‐phase flows Int. J. Numer. Methods Fluids (IF 1.808) Pub Date : 2020-12-07 Nilesh Potghan; C. S. Jog
In this work, we develop a numerical strategy for solving two‐phase immiscible incompressible fluid flows in a general arbitrary Lagrangian‐Eulerian framework. As we use a conforming mesh moving with one of the fluids, there is no need to track or reconstruct the interface explicitly. A sharp interface, discontinuity in the fluid properties, and the jump in the pressure field are all accurately modeled

This paper demonstrates the characteristics of interparticle forces and forcing schemes in pseudopotential lattice Boltzmann simulations. The Yuan‐Schaefer (YS), multipseudopotential interaction (MPI) and piecewise linear methods are examined as techniques of equation of state (EOS) inclusion in pseudopotential models. It is suggested here that it is important to have an understanding of the interparticle
