Re: [dwsim-users] Flash calculation

[Daniel W. <dan...@gm...>]

Hi Urs,

The NL flash uses a nested loops approach to solve PH and PS flashes, i.e.
in an external loop it looks to converge the temperature in order to match
calculated and specified enthalpy/entropy while in the inner loop (PT
flash) it converges the vapor fraction of the mixture using the current
value of the temperature in the external loop.

The IO (Inside-Out) flash is completely different and uses some form of
linearization of the involved equations, see this paper for a reference:
