Can any one give me a name of a journal deal with the non-Newtonian flow and indexed by scopus or thomson publisher

publishing in any journal give us information about the level and the process of this journal.The selection of any journal is not easy task.

How i can insert the effect of nanoparticles in non-Newtonian polymer melt numerically using finite element through ANSYS softwaer?

In analyzing of nano non-Newtonian flow you need to study the effect of nanoparticles on rheological behavior numerically and then campared with expremental work.

How can i measure the molecular weight or the length of the polymer chains directly without and rheological test?

I can measure the length chains from the rheological test through testing of viscosity ,but this give me approximate result, therefore i look for any exact way for that test.

How can i connect between the physical and chemical phenomena in polymer structure and the order of differential equation?

Behavior like swelling, shrinkage, circulation, and rod climbing occurs in polymer as elastic phenomena all can represented by differential equation. Is there any relation between these phenomena...

What is the relation between the surface tension and stability of nanofluids.?some

sometimes the surface tension of nanofluid increases and sometimes decreases with the nanoparticles concentration increasing.There is no constant behavior for that.Is there any useful test about that.
