Abstract

V Lavalovi šobi želimo s pomočjo vakuumske črpalke ustvariti nadzvočni tok, katerega udarni val vpliva na filament in omogoči, da se le ta pravilno prereže ob navijanju. S pravilno oblikovano šobo in dovolj velikim podtlakom lahko dosežemo nadzvočne hitrosti in udarne valove, kar je bilo dokazano s CFD simulacijo toka fluida čez Lavalovo šobo.

Secondary title: Vacuum suction of filaments using Laval nazzle
Secondary abstract: We want to create a sonic flow in Laval nozlle with vacuum. Shock wave caused by the sonic flow is affecting the filament and thus enabling a clean cut at the beginning of winding. With correctly designed shape of the nozzle and great enough vacuum we can achieve a sonic flow and shock waves, which was proofed with CFD simulation of fluid through Laval nozzle.
