Modeling carbon nanotube as particle in fluid

terktor · December 20, 2015, 06:38

Hi.
I want to investigate the impact of geometry of nano particles in the conductivity of nano-fluids. i want to use single and multiple wall carbon nano tube as a nano particle. the nano fluid has no velocity. the volume fraction of nano fluid is lower than 5%.
Unfortunately i am not familiar with modeling nano fluids in Fluent and i dont know how to start modeling such problems.
could you kindly help me how to start solving?
Should i write UDf to define nano particles in fluid? How about thermal conductivity correlation?
Thanks

Did you calculate the Knudsen Number for your problem?
Are you sure your problem is in the realm of continuum mechanics?
Maybe it is in the realm of Molecular Dynamics.
