Note on energy equality of mhd system

WebAug 31, 2024 · 1. 2. In this paper, we study the energy equality for weak solutions to the 3D homogeneous incompressible magnetohydrodynamic equations with viscosity and magnetic diffusion in a bounded domain. Two types of regularity conditions are imposed on weak solutions to ensure the energy equality. For the first type, some global integrability … WebIn this note, we prove that the weak solution (u ,B ) of the MHD system satisfies the energy equality, provided that one of the following assumptions is satisfied: (i) u ,B ∈Lq(0 ,T ;Lp(Ω …

On the energy equality for very weak solutions to 3D MHD

It is reasonable to conjecture that the energy equality of MHD system may hold under other assumptions only on the velocity fields, since [12] showed regularity criteria with assumptions only on \mathbf {u}.
