Euler-Euler and Euler-Lagrangian approach on similar model and comparison
 

I have few question relating to Euler-Lagrangian simulations. I am analyzing solid-liquid flow at 90 degree elbow in pipe with both techniques Euler-Euler and Euler-Lagrangian and i want to see what is the difference in results by using both techniques.



1) In Euler-Euler approach there is an option to mention what is the volume fraction of secondary phase. But in case of Euler-Lagrangian approach how do i mention that my secondary phase is this much?


2) If i want to compare my results for Euler-Euler and Euler-Lagrangian approach then which parameter should i compare. I was comparing maximum pressure in elbow for Euler-Euler and Euler-Lagrangian approach but i found out that i can find it in Euler-Euler approach but in case of Euler-Lagrangian approach it is not available. Only pressure available was of liquid phase which was solved by Eulerian method. So, my question is how can i measure the combine pressure due to both phases.


Please do reply, I will really appreciate.
