| Abstract: | The FEMLAB software is a professional finite element numerical simulation software package which was made by COMSOL Multiphysics.It is based on differential equation's scientific and engineer problem,through modeling and imitating real calculation under alternative exploitation environment system.Using FEMLAB software carry through three-dimensional parameter modeling to labyrinth emitter,modeling flow analysis,pressure-flux relations,frame analysis,velocity of flow distributing and anti-clogging performance,process parameter logical choice and confirm,which could constitute parameter douche frame and performance relationship modeling,obtaining manufacture design motive. |
