WebJun 1, 2024 · 1. Introduction. Magnetohydrodynamicpower (MHD) generation is based on Faraday’s law of electromagnetic induction, with the working fluid in this device being a … 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.
WebThe paper concentrates particularly on sources of fixed frequency, and solutions satisfying the radiation condition; but an Appendix is devoted to waves generated by a source of finite duration in an initially quiescent medium, and to unstable systems. WebNov 1, 2012 · 5. INTRODUCTION Magneto hydrodynamics (MHD) (magneto fluid dynamics or hydro magnetics) is the academic discipline which studies the dynamics of electrically conducting fluids. Examples of such fluids include plasmas, liquid metals, and salt water. The word magneto hydro dynamics (MHD) is derived from magneto- meaning magnet ic …
