旋流器是一种高效低耗的分离设备,在工业领域中具有广泛的应用。以数值模拟为研究手段,运用计算流体力学软件(FLUENT)研究改进型旋流器的内部流场特性,重点对旋流器结构造型的改变所造成的内部速度场和压力场的分布规律进行了研究,分析了旋流场内部循环流和盖下流的分布特征,进而掌握旋流场内部规律的本质。为改进型旋流器的开发和设计奠定了基础,有利于数值模拟技术在产品造型设计中的推广。
Cyclone is a high efficiency and low consumption of separation equipment, has a wide range of applications in the industrial field. Taking numerical simulation as the research method, FLUENT was used to study the internal flow field characteristics of the improved cyclone. The distribution of the internal velocity field and pressure field caused by the change of the structure of the cyclone was focused Studied and analyzed the distribution characteristics of internal circulation flow and cover flow in the swirling flow field, and then grasped the essence of the internal regularity of the swirling flow field. It laid the foundation for the development and design of the improved cyclone, which is helpful for the popularization of numerical simulation technology in the product design.
