Weakly Nonlocal Irreversible Thermodynamics
نویسنده
چکیده
Weakly nonlocal thermodynamic theories are critically revisited. A relocalized, irreversible thermodynamic theory of nonlocal phenomena is given, based on a modified form of the entropy current and new kind of internal variables, the so called current multipliers. The treatment is restricted to deal with nonlocality connected to dynamic thermodynamic variables. Several classical equations are derived, including Guyer-Krumhansl, Ginzburg-Landau and Cahn-Hilliard type equations.

متن کاملWeakly Nonlocal Irreversible Thermodynamics- the Ginzburg-landau Equation
The variational approach to weakly nonlocal thermodynamic theories is critically revisited in the light of modern nonequilibrium thermody-namics. The example of Ginzburg-Landau equation is investigated in detail.
متن کاملWeakly Nonlocal Irreversible Thermodynamics- the Guyer-krumhansl and the Cahn-hilliard Equations
Examples of irreversible thermodynamic theory of nonlocal phenomena are given, based on generalized entropy current. Thermodynamic currents and forces are identified to derive the Guyer-Krumhansl and Cahn-Hilliard equations. In the latter case Gurtin's rate dependent additional term is received through the thermodynamic approach.
