主　　题：Polymeric fluid Internal viscosity Extensional viscosity. 

摘      要：The dumbbell model with internal viscosity for a dilute polymer solution is investigated based on a balance of viscous drag and restoring Brownian *** approximate method is used to obtain the solution of extensional stress in closed form in the case of steady *** different internal viscosities,this parametric study shows different asymptotic regimes of the extensional viscosity as a function of strain *** analysis may explain the attenuation of pressure drop in strong flows from a phenomeno...
