Teorie elektrodifuzních čidel třeni v mikrodisperzních kapalinách 8. Vliv zdánlivého skluzu na směrové charakteristiky
Wein, Ondřej
Insulated insertions between individual segments of direction-sensitive electrodiffusion friction probes attenuate the directionalsensitivity. Quantitative study of this effect by Wein and Wichterle (1989) for Newtonian liquids has been extended in a recent research report (Wein 2007) for the microdisperse liquids, displaying the Apparent Wall Slip, i.e. a non-linear velocity profile close to solid surfaces. In the present research report, this theory is used to the simulation calculations of directional characteristics for a class of 3-segment electrodiffusion friction probes with the insulating insertions. Rather realistic model of non-ideal 3-segment direction-specific probes is tested by comparison of the predictions with experimental data about an actual 3-segment probe in both homogeneous and microdisperse liquids.
