| Abstract: | Non-Newtonian effects on the breakup of jets into drops were experimentally studied for power law fluidNdashNewtonian systems under the condition of zero jet velocity relative to the continuous phase. While laminar breakup lengths of Newtonian jets in non-Newtonian liquids agree with the prediction from the stability analysis for Newtonian systems, non-Newtonian jets in Newtonian liquids are less stable than Newtonian jets. Experimental diameters of drops formed from jets in NewtonianNdashnon-Newtonian and in non-NewtonianNdashNewtonian systems are in good agreement with the prediction based on stability analysis for Newtonian systems. |
