The modeling of MHD phenomena is intrinsically a multiphysics problem; one must numerically solve for the coupling between fluid flow, current flow, and magnetic fields. In the space surrounding the moving fluid, there is no current flow, so we only need to solve the single vector equation: where \mathbf{B_r} is the remanent flux density, which is only nonzero in the magnet domains. The magnetic and electric fields are both described using second-order discretization. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this. An MHD problem of a conductive fluid in a channel between two magnets with applied current. This means that the fluid flow problem does not affect the current, which means that the flow equations can be solved entirely separately from the electromagnetic field equations. There are two electrodes protruding through the flow channel on either side that drive an electrical current through the fluid by applying a potential difference.

Magnetohydrodynamics couples electro-dynamics with fluid mechanics through the Furthermore, this example may also be defined and modeled using components from the following product combinations: The combination of COMSOL products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Most of the comparisons have demonstrated good qualitative and often quantitative match with the available experimental, analytical and numerical data. The open boundary condition should be sufficient. However, if we assume that the former term is much larger than the latter (that is, \nabla V \gg \mathbf{v \times B}), then we simplify the current equation to: \mathbf{J} = \sigma \left( \nabla V \right) . COMSOL Multiphysics version 6.1 including expanded capabilities in Fluid and Mechanical Simulations. My boundary conditions are V=V0*e_theta (azimuth) resulting in a rotating wall and B=0 (kind of a no-slip condition).

The study of the interaction of magnetic fields and electrically conducting liquids or gases, such as molten metal or plasma. In addition to these induced currents, there are currents that arise as a consequence of the boundary conditions on the electric potential field, V, so that the total current in the fluid becomes: This current, flowing through the magnetic field, will lead to a volume force on the fluid of \mathbf{F = J \times B} , and this will act to pump the fluid from one reservoir to the other. The post by Youcef Attou is very insightful and it can save a lot of time for those who want to do MHD using COMSOL. listed if standards is not an option). Y. Yan [1], S. Smolentsev [1], M.

Waves 5 Traditionally close link Mathematics - Astronomy I would like to share my experience of using COMSOL to analyze the tokamak start-up physics, in particular the ECRH assisted plasma pre-ionization. Of course, these assumptions and simplifications that weve made do have their limitations, so it never hurts to check against a full model, but the power and flexibility of the COMSOL Multiphysics platform let us easily build both simplified and complete models, compare them, and modify them in whatever way we desire. The solution time will be greatly reduced when solving this simplified case, as compared to the fully coupled case, since the physics equations are solved separately and the software does not need to iterate between them. My initial conditions are such that I have V=V0*e_theta (azimuth) and a magnetic field described by a gaussian function B=B0*e_z (with B0=e^(-r^2/d^2) where d=1) on the inlet. We observe a distinct pumping effect: The applied voltage causes current to flow through the fluid, and as these charges move through the magnetic field, they experience a force, which is imparted to the fluid. . This model example illustrates applications of this type that would nominally be built using the following products: however, additional products may be required to completely define and model it. This comprehensive textbook emphasizes physical ideas, rather than mathematical detail, making it accessible to a broad audience. | Meaning, pronunciation, translations and examples If you don't know what COMSOL is this.. For this problem, we need to solve a system of partial differential equations within the fluid to describe the electric and magnetic fields. Introduction 2. Sometimes this can be achieved simply by using built-in features of the software, but in other cases, the user will need to do a little bit of extra work. The Magnetic Fields, No Currents interface defines the equation \nabla \cdot \left( \mu_0 \mu_r \mathbf{H + B_r} \right) = 0, which is much less computationally expensive than the set of equations defined in the Magnetic and Electric Fields interface. Introduction; 2. The word magnetohydrodynamics is comprised of the words magneto- meaning magnetic, hydro- meaning water (or liquid) and - dynamics referring to the movement of an object by forces. A new interface enables the analysis of battery packs with several hundred cells. The equations of MHD are derived in both case of the cylindrical coordinate and Cartesian coordinates. ( 5.4) () In this study, we perform various tests to address the COMSOL capability to adequately resolve LM-MHD flows in strong magnetic fields under steady and unsteady flow conditions. The fundamental principle of magnetohydrodynamics is that magnetic fields can induce the electric current in a dynamic conducting field which in turn polarizes the fluid and as a result of the polarization in turn it will also change the magnetic field. We will assume that the flow is laminar and thus solve the NavierStokes equations in the channel domain. Induction pumps are used in high temperature cooling systems.
