WebJan 14, 2024 · We perform MHD simulations to study the dynamical evolution of the magnetic field and compute the resulting SGWB. We show that the SGWB output from the simulations can be very well approximated by assuming that the magnetic anisotropic stress is constant in time, over a time interval related to the eddy turnover time. WebThe LES results show that the t-1 decay of [] starts after five eddy turnover time that corresponds to 1330 UTC ending at ten turnover time or 1430 UTC. The t -2 decay is a very rapid stage, it holds just for a short interval and finally, when the temperature stratification get stronger, the decay rate goes to the final stage characterized by a ... tinikling wall decor
