Onsager variation principle
Web21 de nov. de 2024 · Onsagers variational principle (OVP) was originally proposed by Lars Onsager in 1931 [L. Onsager, Phys. Rev., 1931, 37, 405]. This fundamental principle provides a very powerful tool for formulating thermodynamically consistent models. It can also be employed to find approximate solutions, especially in the study of soft matter … Web28 de jun. de 2024 · However, the Onsager variational principle [5,6,7,8] is widely applied to various fields [9,10,11,12,13,14]. It is because the Onsager variational principle is a variational theory different from the Hamilton principle. However, it is hard to find a literature for a systematic derivation of the Onsager principle, except Eu and Ichiyanagi .
