| contents | In this study, a magnetohydrodynamic model is developed to study the dynamics of vortices driven by edge-current. Two modeled equations for fluid and magnetic field variables are each transformed into diffusion equation for vorticity and poisson equation for stream function. A numerical solution method is designed using a simplified Lattice Boltzmann method (LBM). The LBM-D2Q5 scheme is utilized to obtain the numerical solutions for the fluid and magnetic field variables. Understanding the hydrodynamic behavior of systems employed in vortex-based memory systems is crucial for reliability and performance optimization. Based on this motivation, the effect of applied edge-current on the hydrodynamic and magnetic vortex configurations are analyzed through numerical simulations. The impact of the boundary magnetization is also conducted, by varying the strength of the magnetic field at the bottom boundary. The obtained graphical results provide some insights into the design and operation of vortex-based memory systems for next-generation data storage applications. |
