主　　题：salt-tolerant partially hydrolyzed polyacrylamide steady-state flow shear thinning FENE-P model 

摘      要：The rheological properties of salt-tolerant partially hydrolyzed polyacrylamide(HPAM)solutions with molecular of 2.5×107 g/mol at different concentrations were measured in steady-state shear flow mode by Haake Rheostress 150 *** constitutive equations(Oldroyd four constant model,Guesekus model and FENE-P model) were used for describing the apparent viscosity and first normal stress *** apparent viscosity of salt-tolerant HPAM solutions appears a first Newtonian zone when the shear rate is approximately lower than 0.2 *** high shear rate,the HPAM solutions show shear-thinning and *** results show that the FENE-P model has the best agreement between theoretical and experimental data within the available shear rate *** material parameters are useful for numerical analysis of polymer solution flow fields.
