CFD simulations were used to analyze the existing nozzle geometry and a new Laval nozzle design was developed that enables an improved suction effect above the sound barrier. Prototype tests confirm a stable increase in production speed of 20% &#8211; limited only by other system components.  <\/p>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<\/div><\/section>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n    <section  class=\"section-desc\">\n\t\t<div class=\"container\">\n            <div class=\"section-desc-wrap\">\n\t\t\t\t\t\t\t\t\t<div class=\"col\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<h2> \n\t\t\t\t\t\t\t\t<mark>Initial situation and requirements<\/mark>\t\t\t\t\t\t\t<\/h2>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"block-desc\">\n\t\t\t\t\t\t\t\t<ul>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li>Product of the system: spun multifilament thread<\/li>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li>Goal: Increase production speed<\/li>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li>Component: Texturing nozzle with suction effect using compressed air to tension the thread<\/li>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li>Problem: Air pressure is increased, but no increase in suction effect =&gt;
