simulate nanofluids with mixture model
hello. I want to simulate cuo nanoparticles dispersed in 60:40 Eg/W base fluid with mixture model. I defined 2 fluid materials for base fluid and cuo nanoparticles but I don't know what value to set for viscosity of cuo! Should I set it to zero?
and also should I activate the granular option for it? I tried both ways, but after running, the viscosity of the mixture is wrong and it is almost equal to the viscosity of the base fluid. what should I do? |
The nanoparticles are dispersed in the water/ethylene glycol mixture. The solid particles themselves do not have viscosity perse. The liquid mixture will of course. Generally nanoscale size particles will follow the flow very well unless acted upon by an outside source. If you are setting your model up with Copper Oxide nanoparticles as a component in a mixture, leave it to what your use for the liquid mixture.
What is the particle loading in your model? How are you attempting to model the particles? Will you be using the Population Balance models? What are you attempting to see in the results? All of these really go to answering the question. |

What are your recommendations for simulating nanoparticles in the mixture method? |
Do you know how the changes in viscosity and heat conductivity will change as a function of particle loading? For what you mention, I do not see any reason to explicitly model the particles. It would simply be different simulations with different material properties based upon the amount of CuO in the stream. Is there a reason why you need to include the particles?
