Mixture Model For Nanofluid

Heat Pipe · May 5, 2015, 10:19

Hi Guys
I wanna simulate a model of 3D-Tube and the fluid is (Water+Cuo), the solid nanoparticles has a diameter = 20 nm. How to perform simulations by using Fluent. I know the basics but need a good tutorial about this issue.

I used Eulerian model even mixture model not difficult just read few steps in user guide you just need to set boundary conditions and set the granular phase droplet diameter for the nano particles?

Hello,

I am working with external flow of nanofluids around cylinders. I am using multi-phase flow models in FLUENT. To be precise, I am using Eulerian and Mixture model.

But, I am observing a decrease in C_D and Nu_M, when I increase the Particle volume fraction. (Re - 10 to 40). This is in contradiction with the literature and basic behavior of nanofluids. Kindly, please help me solve this.

I am afraid i am not familiar with your problem i solve internal flow problem and you solve external flow problem? I hope somebody else assist you?

hi all, i have the sameproblem pleaase how you fixed this problem i did all steps but i have a problem of divergence.
Can you give me a tutorials can help to resolve this problem
thnak you
