Research on Magnetohydrodynamic turbulent Behavior; Development of the turbulence model using Large Eddy Simulation

Tanahashi, Takahiko*; Miyoshi, Ichiro*; Ara, Kuniaki ; Ohira, Hiroaki

Investigation of Magnetohydrodynamic (MHD) turbulent model applying Large Eddy Simulation (LES) method was started in FY15 in order to evaluate MHD turbulent behavior on the conditions of high Reynolds numbers and high magnetic Reynolds numbers. In FY15, a proposed Subgrid Scale (SGS) model for direct magnetic fields was applied to Generalized Simplified Marker and Cell (GSMAC) method to Finite Element Method (FEM). A Direct Numerical Simulation (DNS) method was also developed to verify the theory and create a new SGS model.
