Numerical Simulation of MHD Turbulent Flow in a Rectangular Channel with Three-Surface-Coated Multi Layers
Краткое описание
A rectangular channel with three-surface-coated multi layers has been proposed to reduce the MHD pressure drop in the liquid metal blanket system. In this study, the turbulent flow and pressure drop characteristics are investigated with changing the orientation of the magnetic field by numerical simulation, where a k−ε model containing the effects of the magnetic field is employed. The simulation is conducted under the conditions; the Reynolds number of 4494 and the Hartmann number of 20.9 or 52.2. The inclination of the magnetic field (θ) is changed from 0° to 90°. At an inclination of θ = 45°, turbulence viscosity becomes the highest due to the velocity distributions with more turbulence kinetic energy production. The pressure drop increases when θ is larger than 30° by the electromagnetic force, especially in the case of higher Hartmann number.
