do we have an option in Ansys fluent for assigning the diameter of the particles without using the Eulerian phase model?

I was simulating nanoparticles laden phase changing material with two different phases by using the volume of the fluid model. but I can't specify the diameter of the nanomaterial though I can specify the volume fraction. 

any suggestion

VOF is a free surface tracking model, so there isn't a diameter to set. What phases are you wanting to include in the model?

One is the phase changing material (initially solid), and other is solid particles of diameter  10 nm.

So no coherent free surface? Please read how the VOF model works. You may also want to review the DPM model.
