Abstract

This paper continues the description of a two parameter family of solutions for the local asymptotic behaviour of previous termUCMnext termprevious termfluidsnext term at re-entrant previous termcornersnext term. Here, the natural stress basis is used to re-derive the equations in the core previous termflownext term and boundary layers, with full description of the scalings and matching being given. The parametric solution dependence is completed with numerical deteremination of the coefficient of the downstream wall shear rate. The previous termflownext term structure implicitly assumes the absence of a separating streamline in the upstream region.
