Abstract/Summary Tangential air shear on the inside of a stationary cylinder, as may exist in the annulus between a concentric rotating and stationary cylinder, can be used to establish a fully wetting film. At low shear a liquid pool is formed at bottom dead center, while at high shear the pool is spread into a film. The development of a thick film model for such conditions is presented. Within the model momentum, gravity, pressure, and wall and air shear are considered to obtain a steady state film solution. Results for a range of operating conditions are presented. Finally by considering the stability of the film solutions as air shear is reduced, the lower limit for film solutions is investigated.
