Ceramic materials provide an innovative opportunity for corrosion-resistant coatings for nuclear waste containers. Their suitability can be derived from the fully oxidized state for selected metal oxides. Ceramic coatings applied to plain carbon stee

The creeping plane flow of two viscous cylinders coalescing under the influence of surface tension is described theoretically in a series of three articles. Part I is a theoretical overview. The physical assumptions affecting applicability of the the

The theoretical geometry of the creeping plane-flow coalescence of two viscous cylinders driven by surface tension is described. Normalized results are given for initial diameter ratios D = (1,2,5,20, [infinity]). Typical shapes are displayed. Time-d

For the free creeping viscous incompressible plane flow of a finite region, bounded by a simple smooth closed curve and driven solely by surface tension, analyzed previously, the shape evolution was described in terms of a time-dependent mapping func

The coalescence of a cylinder with half-space by creeping viscous flow driven solely by surface tension is analysed using methods developed previously. The evolution of the shape with time is described, exactly, in terms of a time-dependent mapping f
