Abstract: Abstract Measurements are performed on film thickness and free surface velocity around a rotating roll for Newtonian, non‐Newtonian inelastic, and viscoelastic fluids by using noncontact methods of a capacitance probe and a laser Doppler velocimeter probe. The film thickness decreases with increasing inspection angle for Newtonian fluids. For non‐Newtonian fluids, it retains an approximately constant value, owing to shear‐thinning of viscosity, except for a meniscus region development, which is dependent on f…
