The rheology of oils during impact II. Silicone fluids

Abstract

The behaviour of a series of silicone fluids has been examined in the apparatus described in part I. The fluids exhibit non-Newtonian properties and the theory applicable in part I is not able to explain their behaviour. The theory for a power law fluid is developed and shown to be in accord with the experimental results; the experimental observations enable values of the model constants to be deduced.

Squeezing flows of polymeric liquids

“…A complete numerical solution of both the equation of motion using the power law and the energy equation has been given kor squeezing flows by Booth and Hirst (1970b). Their method ok solution follows that of Gould (1967), who solved the problem for a Newtonian liquid.…”
