文丘里洗涤器压力损失的计算

Calculation of the Pressure Drop in Venturi Scrubbers

在进行文丘里洗涤器设计或结构优化时,准确地预测其压力损失数值大小非常重要,多年来一直受到众多研究者的关注。本文对国内外用于计算文丘里洗涤器压力损失的研究成果,即经验关联式、解析解法与数值解法进行了简单地介绍,并将由不同的计算方法得到的预测值与本文作者实测的数据进行分析比较,以期为设计者在进行文丘里洗涤器设计或优化操作时选用合适的计算方法提供理论参考。

Accurately predicting the pressure drop, which has been attracting the attention of many researchers for several decades, is very important when designing or optimizing the operation of a Venturi scrubber. The purpose of this paper is to introduce the most important methods available for the prediction of pressure drop in Venturi scrubbers. In addition, the predicted values of various methods are compared with the experimental data from Venturi scrubbers of different sizes under operating conditions for the purpose of providing theory groundwork for practical design.
