Abstract:
For the final purpose of making clear a mechanism of weft yarn insertion in a water-jet loom, the flow and configuration of the jet in the vicinity of the nozzle exit have been analyzed by utilizing the matched asymptotic expansion technique. Since in the present analysis the flow field, the nozzle profile, and the weft profile have been idealized, the results cannot indicate the actual phenomena in a strict sense. However, the following results have been obtained. The flow is per turbed by using the small parameter (the reciprocal of the cube root of the Reynolds number). The decreases of the radius of the core-flow region, the jet-radius, and the acceleration of the flow velocity near the free boundary of the jet have been calculate as a function of the distance from the nozzle exit. In order to calculate in detail the weft-insertion force, the other region near the weft surface is to be taken into account.
