▪ Abstract Coating is the process of applying thin liquid layers to a substrate, often a moving
web. Complex coating processes can be approached through examination of their fluid …

We present the results of a combined theoretical and experimental investigation of the
influence of surface tension the acceleration due to gravity. The theory of viscous hydraulic …

We present the results of an experimental investigation of the striking flow structures that
may arise when a vertical jet of fluid impinges on a thin fluid layer overlying a horizontal …

When a vertical jet of liquid from a nozzle hits a flat surface, as in tap water striking the
kitchen sink, a discontinuity appears in a ring created by the flow. At this deformation the …

I present the theoretical evidence which suggests that gravity is an emergent phenomenon
like gas dynamics or elasticity with the gravitational field equations having the same status …

Conservation equations are written for surface flows (either fluid or granular). The
particularity of granular surface flows is then pointed out, namely that the depth of the flowing …

We provide an experimental demonstration that the circular hydraulic jump represents a
hydrodynamic white hole or gravitational fountain (the time reverse of a black hole) by …

When a laminar inclined circular jet impinges on a horizontal surface, it forms a non-circular
hydraulic jump resulting from the non-axisymmetric flow. In this study, we develop an …

We reformulate shallow water theory to understand viscous shear induced natural hydraulic
jumps in channels slightly deviated from the horizontal. One of the interesting contributions …

We examine the structure of the continuous circular hydraulic jump and recirculation for a jet
impinging on a disk. We use a composite mean-field thin-film approach consisting of …
