| Abstract: | The work performance and request of cold-trap in vacuum freezing-drying machine were analyzed.Then,the physical model and governing equation of fluid motion for cold-trap chamber were established.The Fluent simulation software was used to simulate and analyze air-flow organization of cold-trap chamber.Compared with air-flow organization in cold-trap chamber that has guide plate and not,the result indicates that using guide plate can improve air-flow organization effectively to make flow field get more and more uniformity in cold-trap chamber. |
