Multiphase(solid-liquid)model for pipes-elbows system
 
1 Attachment(s)
I have a system which includes pipes and elbows. I will put nanoparticles in water. However I don't know how can I model this system with fluent ?
What I know?
1)I will analyze only pressure-drop effects with particles on flow.(dont need to use temperature)
2)I will use eularian multiphase model. (but how?)
3)Particle distribution should be random
4)Flow type is turbulent

I dont know how can I write UDF and some other things
And also which drag coefficient should be selected ?
If some one helps me I will be very happy
Have a good day

help please !!!!
 
I need quick help to complete my project please attention

Why do you insist on Eulerian model? If your nanoparticles have smaller volume fraction (less than 0.1) you can use DPM for this and it will be a lot easier!

thanx
 
Thank you for your answer. However I had completed my project with Eulerian method before you answered :)

Hi,

Can you please tell me what value of viscosity for solid phase you use?
