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 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.

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.

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.

How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...
