Numerical Simulation of Non-Newtonian Inelastic Flows in Channel based on Artificial Compressibility Method
In this study, inelastic constitutive modelling is considered for the simulation of shear-thinning fluids through a circular channel. Numerical solutions are presented for power-law inelastic model, considering axisymmetric Poiseuille flow through a channel. The numerical simulation of such fluid is performed by using the Galerkin finite element approach based on artificial compression method (...
متن کاملmultigrid method to solve free surface flows
in recent years, many different methods have been developed to simulate free surface flows coupled with moving bodies. in this paper, for simulating ship maneuver, vof method (cicsam) and also for coupling velocity field and pressure a fractional step method are used. to increase simulation accuracy, the mesh size should be significantly fine. unfortunately, fine grid causes increase in simulat...
متن کاملThree-dimensional characteristic approach for incompressible thermo-flows and influence of artificial compressibility parameter
In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity equation, Momentum equations in three directions, and energy equation) and then results ...
متن کاملLink-wise artificial compressibility method
The Artificial Compressibility Method (ACM) for the incompressible NavierStokes equations is (link-wise) reformulated (referred to as LW-ACM) by a finite set of discrete directions (links) on a regular Cartesian mesh, in analogy with the Lattice Boltzmann Method (LBM). The main advantage is the possibility of exploiting well established technologies originally developed for LBM and classical co...
متن کاملA Conservative CIP Method for Violent Free Surface Flows
In the past several years, continuous effort has been made in RIAM, Kyushu University to develop an efficient Cartesian grid method for violent free surface problems in ship and ocean engineering. Our researches have been focused on (1) Accurate and robust flow solver for multi-phase flows with solid bodies. (2) Conservative and smearingless interface capturing scheme. In the numerical method, ...
