Abstract:
The flow and rheological characteristics of gel simulation in the pipe were simulated by using POLYFLOW software．The result shows：the pressure loss linearity increase with tube length when velocity and diameter are invariable．The pressure loss reduces rapidly with diameter increase when velocity and pipe length are invariable．The plug flow area is existed obviously at axes area along with power law index increase．In this area，the change of velocity and shear rate is smaller，and the shear viscosity is the biggest．In the area of pipe wall，the changes of velocity and shear rate are tempestuousness，and the shear viscosity decreased obviously．
