摘要

本文讨论了气体流化床中立管与充气间压力波动耦合的解释。以前的实验已经注意到，在一定条件下，在分配器下面的静压室(也称为风窗)中，由于气泡爆发而在立管中发生的压力波动也被观察到。为了解释这种耦合取决于床层和空气分布器设计以及流动特性的有效性，我们开发了一个简单的模型，并与下面的实验相关联。

About frequency coupling between riser and plenum in a gas fluidized bed

This article deals with the explanation of pressure fluctuations coupling between riser and plenum in a gas fluidized bed. It has been noticed by former experiments that the pressure fluctuations taking place in the riser due to bubbles eruptions is also observed underneath the distributor, in the plenum (also called windbow) under certain conditions. In order to explain how effective is the coupling depending on the bed and air distributor design but also on the flow characteristics, we have developped a simple model associated to an experiment presented hereunder.
