Hi,

Can Mixture model (FLUENT) can be used for simulation of nanofluid?
I've heard that mixture model is for particles of micro in size.

I have the same question with Waqas Ahmed. I plan to use FLUENT for simulation of nanofluid heat transfer, but i'm not sure the mixture model is applicable for nano-sized particle.

[rezacfd1361]

what s the meaning of selecting sum in "define surface monitor" for "Phrases" , "volume fraction" . I have a 2 phase domain, primary phase is air and secondary phase is water. I am going to track surface changes for water, in internet i read that I have to select sum when i intoduce monitors/surface/surface monitors/define surface monitor.
my case is a Neumerical Wave Tank.
please help me.

Dear all,

I'm simulating nanofluid (Alumina water-based) using mixture model. The primary phase (water) and the secondary phase (alumina-2%). Eventhough the volume fraction of alumina is very small, the particle diameter is larger enough compared to water.

dia. of water molecule=0.29 nm, dia. of alumina=20 - 40 nm.

In mixture model, i'm defining both properties as individual property(not mixture properties). What make me confuse here is that from lit. review, all papers shows the eff. thermal properties (mixture properties) instead of individual properties.

Am I doing wrong here?Should i define the mixture or individual properties? In fluent tutorial, they use individual properties.

Thanks in advance

I have the same problem, how to use mixture model for nanofluids in Fluent?

[HyperNova]

hi , could any body here solve the problem with mixture model in nanofluid modelling ? thanks

[saurabhg2014]

You found any solution?

[HyperNova]

who ? me ?!

You can see this paper:
http://www.sciencedirect.com/science...3519331400284X
Mixture model in FLuent has been used for nanofluid.

[TRINAVEE]

WHERE CAN THE PARTICLE VOLUME CONCENTRATION eg 1% ,4% BE given FOR NANO FLUID here in fluent ?

[TRINAVEE]

i have the same doubt .please help

@gautam did u solve ur problem?

[HyperNova]

if the volume fraction is less than 2 percent, DPM can be used in my opinion. But one should be careful with interfacial forces like drag law.
