Keywords: Thin film flow | PTT fluid | Exact Solution

This paper investigates the exact solutions for the thin film flow of PTTfluid having zero solvent viscosity, in two cases: (i) down an inclinedplane and (ii) on a vertically moving belt. The problems are solvedtaking into consideration both the linear and exponential PTT models.Expressions for important physical quantities such as velocity, volumeflow rate and average velocity are also reported.
