Turbulent mixing from breaking oceanic internal waves drives a vertical transport of water are major sources of energy for the internal wave field.
10 Jun 2002 [1] Using a parameterization for internal wave energy flux in a hydrodynamic model for the tides we estimate the global.

Internal Energy and Heat Capacity of the Canonical Ensemble . of mixing which suggests that ln ? is related to entropy.
The Gibbs energy in the form of the chemical potential is the basis of phase equilibrium calculations in chemical engineering while formulations of the Helmholtz energy have been preferably applied to corelater wide-ranging data and properties of pure fluids with high accracy u Schu formulations are implemented in the current state-of-
The Gibbs energy of mixing two ideal liquids A and B is: mix G = nRT( x A ln x A + x B ln x B) The corresponding entropy of mixing is: mix S = – nR( x A ln x A + x B ln x B) The corresponding enthalpy of mixing is: mix H = mix G + T mix S = 0 An excess function (XE) is the difference between the observed (real) function of mixing and the ideal
Thermodynamics of Mixing Let’s think of the lattice model in the book – simulates a liquid of two different things There are N total sites each filled with either an A or a B molecule (sketch lattice) N = NA + NB Let’s think about the entropy of the situation What are the number of arrangements? W = N! / NA!NB! What about A and B
schematic of mixing and the total energy bud-get The salient point here is that stirring is a reversible process between kinetic and potential energy whereals dissipation di?usion and mixing are irreversible (and thus one-way) processes This means that the process of mixing permanently re-moves kinetic energy from the system increasing
The average intrinsic properties of a mixture can be classi?ed using either a molar base or a mass base For instance the internal energy per unit mass of a mixture u is determined by summing the internal energy per unit mass for each species weighted by the mass fraction of the species u ¼ U m ¼ P i m iu i m ¼ X i y iu
mixing there are ? possible states using the Boltzman expression for entropy we have Sterling’s approximation can be used to simplify this expression so where x 1 is the mole fraction of component 1 For an ideal gas system with no enthalpic interaction this is the free energy for mixing ?G=-T?S We can consier a probability p(x
