On the melting of solids near a hot moving interface, with particular reference to beds of granular polymers

Abstract

Some similarity solutions are presented for velocity and temperature profiles within the thin film of fluid that forms between a moving hot interface and a melting solid. The use of dimensionless variables brings out the role of various dimensionless groups, in particular when a shear and temperature-dependent viscous fluid is considered. A simplified heuristic method of solution of the full problem for the case of plasticating extruders is discussed. © 1976.
