Note on energy equality of mhd system
WebIn this paper, we study the energy equality and the uniqueness of weak solutions to the MHD equations in the critical space L∞(0,T;Ln(Ω)). We prove that if the velocity u belongs to the critical space L∞(0,T;Ln(Ω)), the energy equality holds. On the basis of the energy equality, we further prove that the weak solution to the MHD equations is unique.

WebNote on energy equality of MHD system Yong Zeng Abstract. In this note, we prove that the weak solution (u,B) of the MHD system satisfies the energy equality, provided that one … 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}. Observations of space and laboratory plasmas [11] also support the opinion that an incompressible three … See more Let \mathbf {f},\mathbf {g}\in L^2(0,T;L^2(\Omega )) and (\mathbf {u},\mathbf {B})\in L^2(0,T;H_0^1(\mathrm{div}\,0,\Omega ))\times … See more ([27, Lemma 3.1]) Suppose that (\mathbf {u}(t),\mathbf {B}(t)) is a weak solution to MHD on time interval [0, T] with 0
