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.

Can i simulate the phases transitions in materials using finite element method through ANSYS software?

Phase transitions is very important to study and explain the change in the material properties. This test is expensive practicaly and its useful if ANSYS do that instead.

Can i cheak the size and shape of Fe3O4 and SiO2 nanoparticles in solution by using UV-Spectroscopy test depend on light absorpsion.?

Befor that i cheak the specification of silver and gold nanoparticles in nanosolution by UV-Spectroscopy test. Can i use the same test with other nanoparticles like Fe3O4 and SiO2?

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.

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.
