Liquid Mixing Caracteristics on Perforated Tray

Abstract

Mixing parameters representing liquid mixing on a perforated tray are discussed experimentally relating to operational conditions and some tray dimensions. The results are as follows :
The fluctuating velocity of liquid measured from impulse response consists of two parts. The one is the fluctuating velocity caused mainly by gas flow. The other is the apparent velocity observed in the presence of liquid velocity distribution.
The Lagrangian time scale may be discussed in connection with the behavior of a liquid element and is found to be correlated with one parameter, namely the fluctuating velocity divided by the square of mean liquid velocity.
