Abstract A whirlpool is a commonly used separator in breweries for removing the hot trub. The separation is performed in a rotary separator, where the cup of tea effect is exercised. It is an accumulation of the hot trub in the central zone of the separator's bottom in the form of a cone. The purpose of this work is to analyze the possibility to introduce a baffle, in order to intensify the phenomenon of the cone formation. Six different shapes of baffle were experimented by placing them in three different locations relative to the inlet. Particle image velocimetry (PIV), a contact-free method for the measurement of the velocity of the flow, was used for examinations. The influence of the location of the baffle on the progress of the flow and the velocity values were determined. The baffle's shape and the location for which the best conditions of the flow appeared were selected.

改进底部漩涡中流动条件的改善：基于粒子图像测速（PIV）的实验研究

摘要 漩涡分离器是啤酒厂常用的一种去除热渣的分离器。分离是在旋转分离器中进行的，在那里进行茶杯效果。它是在分离器底部中心区域以锥形形式堆积的热碎屑。这项工作的目的是分析引入挡板的可能性，以加剧锥体形成的现象。通过将它们放置在相对于入口的三个不同位置，对六种不同形状的挡板进行了实验。粒子图像测速 (PIV) 是一种用于测量流速的非接触式方法，用于检查。确定了挡板位置对流动进程和速度值的影响。挡板'
