  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

The article contains results of a numerical investigation of the presure-flow characteristic of high-viscosity flows for different rates of heat transfer with the environment. The effect of nonmonotonicity of the characteristic ΔP(Vo) on the stability of operation of the die head of extrusion apparatus is discussed.
