Simulation of Computational Fluid Dynamics on Flow Field in Grid Plate in Packed Tower

WANG Yu-bo,QIU Xing-qi,XU Zhan(College of Mechanical and Electronic Engineering,China University of Petroleum,Dongying 257061,Shandong,China)  
To support the structured packing is the fundamental contribution of the grid plate in packed tower.However,both the structure and the size of the grid plate would affect the state of the flow of gas phase that passes the grid plate in packed tower.Using the flow dynamics analysis software,we prove that the gas' state changed specified degrees,which is a kind of turbulent state when the gas phase enters the grid plate.Meanwhile,we find that there are rotational flows and obvious boundary layers of velocity by analysing the flow in the room of the grid plate.
