The long residence time invariably leads to low Reynolds number flows, which makes the backmixing or axial dispersion an important parameter influencing reactor performance.

Witrynapattern, a helical antenna operates in one of two principle modes: the normal mode with the maximum radiation perpendicular to the helix axis; or the axial mode with the maximum radiation in the direction of the axis [1]. The normal mode dominates when the diameter and axial length of the helix are much smaller than a wavelength.
