An Experimental Study Of Constitutive Equations For Viscoelastic Fluids, Julian Orus Doughty

Doctoral Dissertations

Four viscoelastic constitutive equations are examined for their ability to correlate linear dynamic data with non-linear viscosity and first normal stress data. The theories examined are due to Oldroyd; Pao; Bogue; and Bernstein, Kearsley, and Zapas. The concepts and viscometric predictions of each theory are reviewed with more emphasis on the Pao theory due to a lack of discussion in the literature. A summary of classical linear theory is also presented.

Experimental data were obtained on a Weissenberg Rheogoniometer for two materials: solutions of 10 per cent polyisobutylene in Decalin and 12 per cent polystryene in Aroclor. A limited amount …
