Аннотация:We develop an asymptotic solution for the axisymmetric squeeze flow of a viscoplastic Herschel-–Bulkley fluid, extending recent solutions for the Bingham and Casson models, obtained by Muravleva [20,26]. We use the asymptotic
technique proposed by Balmforth and Craster[36] and Frigaard and Ryan [37]. The no-slip and slip yield boundary conditions at the wall are considered. The combined effects of the power index and the Bingham number are investigated. We
confirm numerically obtained solution, using Augmented Lagrangian methods.
