WebbTherefore, we naturally expect that NS-MHD equations are also valid and have physical meaning. The extra terms arising in the NS-MHD equations are considered effective and may be used to explain a number of physical phenomena where the standard formalism failed to decode as we will explore in what follows and in §3. Remark 2.3 Webbeq.

Webb17 maj 2024 · where τ A = 1/v A is the Alfvén time with length of 1 (the length unit) and the Alfvén speed v A = B / ρ.Thus, it is sufficiently large to avoid its influence on the fast dynamics of Alfvénic time scales. As a result, we used ν ρ = 0.05v A in all the simulation in this paper.. No explicit resistivity is used in the magnetic induction equation, but …
