The Numerical Simulation of Small Melt-Blown Machine Spinning Die Bead by Fluent

Abstract:

In the melt-blown nonwoven fabric technology,the design of melt blowing die drawing hot air passage is very important. The design of spinning die rely on mapping and experience currently,when forming the series are often inadequate design basis.In order to obtain the die flow of air jet flow and temperature distribution,this paper analyzes the working principle of the die head assembly and establish three basic equations of jet flow field; got jet flow field velocity profile and airflow temperature distribution,experimental results shows that airflow jet flow field simulation results by Fluent obtained are true and reliable,it can also provide references of similar design.
