Simulation Analysis Of Humidifying Filamentous Material In The Production Process

Filamentous material of this paper subjects to the acrylic fiber as an example, using the spray way in the production process of the humidification. Now in the domestic and foreign countries, the acrylic fiber moisture of regain rate is low, and there is still a certain gap to the standard moisture of regain rate. The domestic and foreign's research in the production process of acrylic yarn wetting to regain rate does not see more. Using the spray can improve the contact of water mist particles and acrylic yarn, in order to improve the moisture regain. Increasing the acrylic moisture can improve the thread galling and static friction, and also can improve the final weight. As the mist humidifier with its unique superiority in the actual use process, and the application is not very extensive. So using the spray to increase the acrylic yarn wetting has broad market space and prospects.The Paper first analyzes the atomization mechanism of water mist, the adhesion mechanism and the coalescence mechanism. Based on the multiphase flow provided model, choosing the right model. Then creating the model in the gambit according to the real pipeline. First.using the Mixture to simulate the distribution of acrylic yarn without humidification and then using the spray model to simulate the distribution under different conditions of water mist in the pipeline.Through the Fluent software simulating and analyzing the low field of the pipeline. Getting the distribution of the concentration of water mist in the different spray droplet size, water temperature and water mist speed, the distribution of acrylic fibers is relatively uniform. If the distribution of water mist is also uniform, then the effect of humidifying is better.
