Abstract The boundary layer of an incompressible fluid in the domain ahead of the departure of the free streamline from the surface of a smooth body or a break-point of its generator, is considered. The potential of the external irrotational velocity field is taken from the theory of jet flows.

Viscous flows occur when the effects of fluid viscosity are balanced by those arising from fluid inertia, body forces, and/or pressure gradients. In such flows, scaling analyses do not allow a priori neglect of any terms in the equations of fluid motion.

AbstractDispersion was studied by subjecting clusters of spherical particles (20–400 μm) to laminar flow fields. The clusters were: cohesionless, consisting of particles suspended in the same liquid as the bulk medium and cohesive for which a different liquid was used to make the suspension. Both qualitative and quantitative results are presented.

Electrosynthesis in Laminar Flow Using a Flow Microreactor
The Chemical Record, 2021AbstractElectrosynthesis and microflow synthesis have become essential tools in their own rights in modern organic synthesis. In this personal account, we summarize our works on the integrated use of these techniques, i. e., electrosynthesis in a flow microreactor.

Riblets are little groves dug on the surface of flying or swimming solid bodies in order to reduce their drag. Why riblets work is not known but it is believed that it is a turbulent process because they trap the main eddies that develop near the solid body surfaces.

Laminar Unidirectional Flow [PDF]
, 1997 Incompressible Newtonian fluid (ϱ η) flows steadily within the annular gap of two infinitely long cylinders (Ro, RI). The outer cylinder rotates with Ω0 the inner one with Ω I . For the case that the axial component of the velocity is equal to zero, calculate a) the velocity and pressure field, b) the moments acting on both cylinders,

Drag reduction using lubricant-impregnated surfaces in viscous laminar flow.
Langmuir, 2014Lubricant-impregnated surfaces (LIS), where micro/nanotextured surfaces are impregnated with lubricating liquids, have received significant attention for their robust, superslippery properties.

Experimental study of the instability of laminar flow in a tube with deformable walls
, 2015The onset of instability of laminar flow in a tube with deformable walls is studied experimentally in order to characterize how the onset is affected by the elastic (shear) modulus of the deformable wall.
