Abstract:The flow in 90? bifurcation pipe are simulated by solving the Navier-Stokes numerical equation with finite element method, which using two ways to generate grids. The calculation results under Reynolds number 1,500 and 500,000 grids are presented, and the content flow structure in 90?bifurcation-pipe flows are given.
