What are the nanoparticles? What do they do to the flow? What is the flow? What do you want to compare?

this modelling is one part of my thesis,i can't explain it detail, i just want to know that do you know how define nanoparticle's viscisity in eulerian model or no,i be thankful you if tell me...

Hi,
I would like to ask is it possible to model a nanofluids heat transfer using the Eulerian-Langragian method? Fyi, I'm trying to study the particle behaviors such as particle collision and particle sticking and their effects on the overall heat transfer in nanofluids. Thanks! Regards, Kamal |

I should write an FAQ on this....
CFX has no nanofluid models. The multiphase model in CFX is a MICRO scale model. It assumes that the lagrangian phase is affected by things like inter-phase slip, particle density and particle mass - these are all micro scale physics. In nano scales things like Brownian motion, surface chemistry, and molecular polarity are important. So if inter-phase slip, particle density, mass and similar properties are important in your case then you can use CFX's multiphase model. If you require Brownian motion, surface chemistry, molecular polarity and all these types of nano scale physics then you have to develop the model yourself inside CFX or use some other software. Particle collision and sticking on the nano scale sounds like Van Der Waal forces to me, along with molecular polarity/ionic stuff. CFX does not have these models, and adding them is not easy (or they would already be in there). |

If you are using Fluent then try the Fluent forums.
Fluent has more models available and is more adaptable so you can add your own models. Thsi is probably going to be easier in Fluent than CFX. |

Oh, so sorry haven't realized that this is CFX forum. I will try to ask around in Fluent forum. Again, thank you.

Can anyone please tell me how to set the size of nanofluid particle in Fluent?
Thank you in advance. |

Have you read any of the posts in this thread? If you have a question about Fluent then try the Fluent forum.

Hi
I want to simulate nano fluid with blood as a base fluid in cylindrical tube under magnetic fluid.the governing forces is magnetic force, buoyancy force, and fluidic force.i want to simulate particle motion in fluent.but I don't know which solver I should use in fluent? Can any body help me? |

this forum is only related to Muti-phase models in CFX?

This is the CFX forum, and it discusses any issue about the CFX software.
Fluent and CFX are bundled together in a typical ANSYS installation now and it appears some people are now thinking they are the same solver - they are not. Questions about the Fluent software should go to the Fluent forum (http://www.cfd-online.com/Forums/fluent/). |
