Webthe Rayleighian with respect to the rates {α˙i} yields a set of kinetic equations X j ζijα˙j = − ∂W ∂αi, i = 1,2,...,n. (4) This describes the force balance between the potential force −∂W ∂αi and the dissipative force ∂Φ ∂α˙i (which is linear in the rates {α˙i}). A simple calculation shows that the variational ... WebMay 25, 2024 · This is Onsager’s variational principle and the function \(\mathcal {R}(x,v)\) is called the Rayleighian of the system. The minimization is performed over the rate of …

Webfunction, called the Rayleighian, which combines the dis-sipation function with the generalized velocities and with derivatives of the energy function. This approach is a variational theory, because it derives the equations of motion by setting certain derivatives of the Rayleighian equation to zero. However, it is not exactly a minimiza- WebApr 19, 2024 · We develop a multi-fluid model for a ternary polymer solution using the Rayleighian formalism of Doi and Onuki, and give an efficient pseudo-spectral method for solving both the diffusion and momentum equations that result.
