An experimental investigation of the flexible blade/gravure roll coating operation is presented for a wide range of operating conditions. The film thickness is measured with an infrared gauge and the data reveal two regions of constant film thickness. At low capillary number (Ca i 0.3). the film thi

## Abstract Coating process is an important step in the manufacturing of different products, such as paper, adhesive and magnetic tapes, photographic films, and many other. The tensioned web roll coating is one the several methods used by different industries. It relies on the elastohydrodynamic ac
This paper analyzes the growth or collapse of a spherical bubble in an incompressibie, viscous fluid. Theoretical results include the timewise variations in the bubble size and its growth or collapse rate, the fluid pressure, and the rate of energy dissipation. The analysis is general and may be app
