Shear Induced Pressure Determines a Reduction in Polymer Radius
Dave E. Dunstan, Dalton J. E. Harvie
Shear induced particle pressure has been measured and modelled for concentrated suspensions of particles. Importantly, the significance of the shear induced particle pressure has n…

The viscosity-radius relationship for concentrated polymer solutions
Dave E. Dunstan
A key assumption of polymer physics is that the random chains polymers extend in flow. Recent experimental evidence has shown that polymer chains compress in Couette flow in a mann…

The viscosity-radius relationship from scaling arguments
Dave E. Dunstan
The viscosity-radius relationship for semi-dilute polymer solutions is derived using scaling arguments. The viscosity temperature and the temperature radius relationships are combi…
