A generalized characteristic based split(CBS) algorithm for incompressible non-isothermal non-Newtonian fluid flows

For well test of non-newtonian fluid , scholars inland and abroad has made a lot of study and acquired lots of results, but these results still can't solve well the practical problems on engineering because of the complexity of the permeability process, so it requires people to make deeper study.

In this paper, we consider a class of compressible non-Newtonian fluids in one-dimensional bounded intervals:with the initial and boundary conditionswhereρ, u andπdenote the unknown density, velocity and pressure, respectively.

Study on oxygen transfer capability of combined impellers in non-Newtonian fluid;

Micromixing characteristics of non-Newtonian fluid in a stirred tank;

Numerical simulation of annulus flow of non-Newtonian fluid in injection allocation regulator corrugated pole;

A study focusing on coalescence phenomena of non-Newtonian fluids and the effect of surface active compounds on the liquid-side volumetric mass transfer coefficient of oxygen in solutions of carboxymethylcellulose(CMC) polymer is carried out in an internal airlift loop reactor.

The bubble behavior in non-Newtonian fluids directly affects mass transfer,heat transfer and the fast and slow of chemical process in fluids.

It was found that with the increase of temperature, the coefficient K of the two kind of non-Newtonian fluids decreases, while the exponent n increases.
