【英文论文摘要】 The flow of HPAM aqueous solution through cylindrical chamber with different parameters nozzles was numerically simulated by FLUENT 6.0.The distribution of velocity, pressure and apparent viscosity in flow field were obtained,respectively.The relation curves between nozzle parameters and velocity,pressure and apparent viscosity were plotted.The influences of nozzle parameters on the distribution of velocity,pressure and apparent viscosity were analyzed.The results show that:with the increasing of nozzle diameter,velocity and pressure drop decrease and apparent viscosity increases;with the increasing of nozzle divergence angle,velocity at nozzle outlet increases,while pressure drop decreases and there is no obvious change on apparent viscosity.水利论文:ug6Av\2_1VU9~
