Helmholtz function is given by
Weblike functional forms that have been developed since the equation of state of van der Waals in 1873 [22]. In this work, Helmholtz energy translations for cubic equations of state are presented. All cubic equations have been handled in a universal formulation. The presented formulations also allow for the use WebThe Helmholtz equation has two forms, the scalar form and the vector form. The scalar form is given as (+ k2)f= 0, where is the scalar Laplacian and fis a scalar function. The vector Helmholtz equation is given as (N + k2)f = 0, where N is the vector Laplacian and f is a vector function. Both forms of the Helmholtz equation
