A turning point asymptotic expansion for a rigid-dumbbell polymer fluid probability configurational equation for fast shear flows
Ionel Sorin Ciuperca, Liviu Iulian Palade · Asymptotic Analysis · 2017
This paper establishes an asymptotic expansion for a second order differential equation with a small diffusion coefficient, which generalizes the configurational probability diffusion equation of the Rigid Dumbbell Model (RDM) of diluted polymer solutions theory for fast shear flows. This is a sing ular perturbation problem with turning point.
