WebFeb 1, 1995 · INTERPRETATION We started the derivation of the loudspeaker driving signal function with the "Rayleighian" postulation that this function is a weighted version of the pressure distribution at the array position, I see eq.(3). The weighting function A n contains a cylindrical spatial divergence factor (r n - r m)-2' see eq.(18), ... Webto x˙, i.e., ∂R/∂x˙ = 0. The function Ris called Rayleighian. The Rayleighian consists of two terms. The first term Φ(˙x) = 1 2 ζx˙2 (7) is called the energy dissipation function. When a particle moves with veloc-ity x˙ in a viscous fluid, it does a work to the fluid per unit time −FHx˙ = ζx˙2, which is immediately dissipated ...

WebFeb 1, 2015 · Onsager principle is the variational principle proposed by Onsager in his celebrated paper on the reciprocal relation. [1,2] The principle has been shown to be useful in deriving many time evolution equations in soft matter physics, [3,4] such as the Chan–Hilliard equations in phase separation, [] kinetic equations in gel dynamics, [] … WebThe Rayleighian is then given by Rp(c˙;c) = Φp(c˙;c)+A˙p(c˙;c). (9) It is easy to check that the relation ∂Rp/∂c˙ = 0 gives Eq. (4). One can also check that the polymer contribution to the stress tensor σp = G(c−I) can also be derived from the Rayleighian by (σp)αβ = ∂Rp ∂καβ. (10) This relation will be used in the next ...
