摘　　要：回旋沉淀槽是一个典型的固液分离设备,是啤酒酿造过程中必不可少的设备之一。研究考查了0~25°进冲角对回旋沉淀槽分离效果的影响,采用CFD技术对回旋过程进行模拟研究,寻找出了回旋沉降过程中的规律性。结果表明：在其他进料条件相同的情况下,随着进料管的进冲角的增大,回旋沉降效果先升高后降低,研究结果可为回旋沉淀槽的设计及优化提供参考依据。The whirlpool separator,which is a typical solid-liquid separation equipment,is one of the requested equipment in beer brewing.This study conducted by Computational Fluid Dynamics（CFD）technology examined the feed tube angles of 0~25° on the separation effect of whirlpool settling vat in order to find swing settlement regularity in the process.Results showed that,under the same feeding condition,the sedimentation effect could be improved by increasing incident angle within a certain degree.Nevertheless,increasing the incident angle to further degree would reduce the settlement effect.The result provides reference for structure design and optimization of whirlpool separator.
