volume_michelsen Subroutine

public subroutine volume_michelsen(eos, n, P, T, V, root_type, max_iters, V0)

Volume solver at a given pressure.

Obtain the volume using the method described by Michelsen and Møllerup. While $P(V, T)$ can be obtained with a simple Newton method, a better approach is solving $P(B/V, T)$ where $B$ is the EoS covolume. This method is easier to solve because: $$V(P, T) \in [0, \infty)$$ and $$\frac{B}{V}(P, T) \in [0, 1]$$
