May 26, 2018, 04:45	Species transfer in the interface of a phase change VOF simulation	#1
Asghari_M Senior Member Mehdi Asghari Join Date: Feb 2010 Posts: 127 Rep Power: 16	Hi all ; Does anyone know how to obtain (govern) species transfer equation (for example for air + water flows) in the interface of phases for a phase change specially based on the volume of fluid (VOF) method? I observed species transfer equation in the papers as follows: $\frac{\partial{}Y_i}{\partial{}t}+\nabla{}.\ \left(\rho{}\vec{v}Y_i\right)=\nabla{}.(\rho{}D\nabla{}Y_i)$ However, I can’t obtain interface condition of above equation between two phases (gas& liquid). I’m pleased if anyone help me to gain a reasonable relation for this purpose. M.Asghari
