CFDsimulation

  利用CFD软件，采用雷诺应力模型分别计算了300型和250型水力旋流除砂器的内流 场，得到了2种水力旋流除砂器的轴向、径向、切向速度及压强的分布曲线。通过对所得结果的 分析，发现模拟结果基本符合旋流除砂器的运行规律。比较2种旋流除砂器的内流场，表明改进 的300型水力旋流除砂器的结构及分离能力优于原来250型水力旋流除砂器，为水力旋流除砂器 的优化设计和选型提供了可靠的设计依据。(use CFD software, Reynolds stress model used to calculate the respective 300-and 250-type sander hydrocyclones the flow field, been two kinds of hydrocyclones sander axial, radial and tangential velocity and pressure in the distribution curve. Based on the results of the analysis, the simulation results are consistent with the Cyclone sander operating rules. Comparing two kinds of Cyclone sander within the flow field, show improved 300 Desanding Hydrocyclones the structure and separation capacity than the original 250-hydrocyclone sander, Desanding Hydrocyclones for the optimum design and selection provided a reliable basis for the design.)
