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: https://www.sciencedirect.com/science/article/pii/S0098135498002221#BIB1 Regards Daniel Em seg., 25 de nov. de 2019 às 10:40, Urs Wagner <or...@gm...> escreveu: > > Hello > > What is the differece between NL VLE and IO VLE flash type? > > Thanks Urs > > > > _______________________________________________ > Dwsim-users mailing list > Dws...@li... > https://lists.sourceforge.net/lists/listinfo/dwsim-users > |
