TRANSPORT IN NON-NEWTONIAN FLOW

Rendering a fluid non-Newtonian by the addition of a high molecular weight polymer alters the heat, mass, and momentum transport characteristics of the fluid. There have been several investigations that have dealt with the determination of the molecular diffusivity in non-Newtonian systems. In a previous investigation, the authors determined the molecular diffusivity of oxygen in aqueous 4% sodium chloride solutions which were rendered non-Newtonian by addition of various concentrations of a completely water soluble polymer of ethylene oxide. In the analysis for the mass transport the molecular flux has been assumed to be linearly dependent on the concentration gradient. To test this, a series of tests was performed at different concentration differences. The experimental results are presented.
