Abstract
The air flow around metallic wire on a carding cylinder was simulated by water flow around transparent plastic model wire of twenty times as large as the metallic wire with the same Reynold's number. Polystylene beads of 0.5_??_1.0mm dia. or aluminum flakes suspended in the water enabled the visualization of the velocity distribution at various section by means of photometry with a slit and a chopper.Comparison between the velocity distribution obtained by the simulation test with the saw-toothed wire model and the distribution obtained by theoretical calculation with a flat wire model as shown in Fig. 6 shows that the drag was maximum at a layer between the tip and bottom of the saw-tooth.From the comparison of these two kinds of velocity distribution, the velocity distribution by the simulation test was expressed by an experimental equation based on the distribution by theoretical calculation with a flat wire model. The ratio of drag-and-friction coefficient of the saw-toothed wire to that of flat wire model could also be obtained from these two distributions.
