Description

Magneto Hydro Dynamic (MHD) & Electro Hydro Dynamic (EHD) ANSYS Fluent CFD Simulation Training Package

This CFD training package, including five practical exercises, is prepared for BEGINNER, INTERMEDIATE, and ADVANCED ANSYS Fluent software users interested in the MHD & EHD modules. You will learn and obtain comprehensive training on how to simulate projects. The achieved knowledge will enable you to choose the most appropriate modeling approaches and methods for applications and CFD simulations.

MagnetoHydroDynamic (MHD)

Magnetohydrodynamics (MHD) is a science that studies the magnetic properties of electrically conductive fluids. The MHD deals with the interaction between magnetic particles within a fluid stream and the magnetic field. In project number 1, the fluid flow field and the magnetic field are combined and influenced by the induction of electric current due to the movement of the conductive material in a magnetic field and the Lorentz force due to the interaction of the magnetic field and the electric current. The present problem first examines the dimensionless Prandtl number without applying the MHD model, then examines the Hartmann number at a constant value of the Prandtl number, followed by the magnitude of the magnetic flux in the presence of MHD. It examines the ratio of electromagnetic force to viscosity force in the model. Finally, at a constant value of the Hartmann number, it looks at the changes in the angle of applying the magnetic flux to the fluid flow.

Project number 2 simulates a magnetic field’s effect on a nanofluid in a channel. A channel is considered two-dimensional. The nanofluid defined in the model is made of iron oxide called Fe3O4 and contains 2% nanoparticles. The magnetic induction method has been used to define the magnetic field in the present work. When this method is used, an external magnetic field is generated to apply a specific magnetic flux in different Cartesian coordinates’ directions.

In project number 3, nanofluid flows in a three-dimensional solid aluminum channel in an applied magnetic field are simulated. Fluid flow is steady and is simulated as one single-phase flow; however, nanofluid’s thermophysical properties are calculated. The surface average of the nanofluid’s temperature equals 293.2 and 304.175K at the inlet and outlet, respectively.

Project number 4 concerns the simulation of airflow around a NACA 0015 airfoil. This airfoil is a symmetrical airfoil that does not produce a lift force at zero attack angle. We investigate the lift coefficient of this airfoil at different attack angles with and without magnetic (MHD) force. In this problem, we study the separation and the maximum angle of attack where the separation does not occur.

ElectroHydroDynamic (EHD)

In project number 5, nanofluid flows in a bumpy channel with an applied electrical potential. Fluid flow is steady and is simulated as one single-phase flow; however, the thermophysical properties of nanofluid are modified. The electrical characteristics of nanofluid alter the fluid mechanic’s behavior of flow, resulting in a heat transfer increase. The surface average of the nanofluid’s temperature equals 300 and 301.926K at the inlet and outlet, respectively.
