Such generators have been operated as sources for … 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 …
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 … WebMHD generators convert heat or thermal energy directly into electrical energy It has no moving parts, so mechanical losses would be minimal Highly efficient Has higher operational efficiency more than conventional generators, therefore, the overall cost of an MHD plant is less compared to conventional steam plants
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.
WebIn this paper, we consider the energy equality of the 3D Cauchy problem for the magneto-hydrodynamics (MHD) equations. We show that if a very weak solution of MHD equations … camp thunderbird washingtonIt 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}.
