Abstract
We derived a general Onsager variational principle in an intuitive and simple manner. Our variational method is similar to the Gauss principle of least constraint rather than the principle of least action. Our result becomes the original Onsager principle if dissipation function is a quadratic function of fluxes and sources. Our result also agrees with previous thermodynamic theories.
