چکیده

As the nuclear fusion research advances, researchers and engineers focus more on design of required systems that complement reaction in plasma a Tokamak. Some proposals for breeding blankets as well plasma-facing components’ protection are based liquid metal flows under Tokamak intense magnetic fields. This creates situation where induced field can be neglected low Reynolds number (Re) electric potential formulation used to close magnetohydrodynamic (MHD) system equations. In last few years, many different laboratories have developed their own MHD codes study flow. A formal verification validation such is necessary enhance reliability numerical results make sure decisions safe grounds. The community has made effort proposing standardized benchmark cases through which any code should demonstrate its reliability. work contains activities some years ago Universitat Politecnica de Catalunya (UPC) currently candidate contribute done at Princeton Plasma Phyisics Laboratory (PPPL). implemented over OpenFOAM makes it easily modifiable. Among these cases, there high Hartmann (Ha), 3-D flows, magneto-convective interaction cases.

Feedback Stabilization and Observer Design for Linearized Mhd Channel Flow at Low Magnetic Reynolds Number

We study a 2D and a 3D incompressible magnetohydrodynamic (MHD) channel flow, also known as Hartmann flow, which is electrically conducting and subject to an external transverse magnetic field. We consider periodic boundary condition along one axis (two axis, for the three-dimensional case). We consider the flow at low magnetic Reynolds number and obtain the so-called simplified magnetohydrodyn...

Tutorial: Verification and Validation for Magnetic Fusion

Dramatic progress in the scope and power of plasma simulations over the past decade has extended our understanding of these complex phenomena. However, as codes embody imperfect models for physical reality, a necessary step towards developing a predictive capability is demonstrating agreement, without bias, between simulations and experimental results. While comparisons between computer calcula...

Low Magnetic Reynolds Number Hypersonic MHD Flow Using High Order WENO Schemes

In this paper we incorporate a low magnetic Reynolds number MHD model to a high order CFD algorithm with WENO and a low diffusion scheme for 3D Navier-Stokes equations. We present results for hypersonic laminar flows around a flat plate and around a blunt body, with different strengths of magnetic fields, to demonstrate the methodology. More simulations, including turbulence, are in progress an...

A numerical algorithm for MHD of free surface flows at low magnetic Reynolds numbers

We have developed a numerical algorithm and computational software for the study of magnetohydrodynamics (MHD) of free surface flows at low magnetic Reynolds numbers. The governing system of equations is a coupled hyperbolic/elliptic system in moving and geometrically complex domains. The numerical algorithm employs the method of front tracking for material interfaces, high resolution hyperboli...
