How to define Liquid-liquid mixture

Marc

Dear all,

I am defining liquid-liquid mixture(NaCl solution and pure water--->mixing). the procedure as follows:

1. give properties of mixture 2. define each species (water and NaCl)

water is easy. i am a bit confused how to define NaCl? i just modify the properties for NaCl based on water from data base? is it correct? if no energy sloved, only density, viscosity, diffustion cofficient are needed?

3. at two velocity inelt, one is to give zero mass fraction of NaCl, the other is to give 10% of NaCl

is it correct?

Your help is highly appreciated!
