RI 7066 Thermodynamics Of Nonlinear Electromagnetic-Fluid Systems

The thermodynamics of an electromagnetic field-fluid interaction system is discussed. A review of the thermodynamics of linear media (the permittivity and permeability taken as functions of density and temperature) is presented; then an extension is made to nonlinear media (the permittivity and permeability taken as functions of the fields). Expressions for thermodynamic properties and reversible work are derived and the first law of thermodynamics for magnetohydrodynamic flow is discussed.
