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.

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.

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.

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,

Aerodynamic Shape Optimization for Natural Laminar Flow Using a Discrete-Adjoint Approach
, 2015A framework for the design of natural-laminar-flow airfoils is developed based on multipoint aerodynamic shape optimization capable of efficiently incorporating and exploiting laminar–turbulent transition.

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.

Flow Laminarization and Acceleration by Suspended Particles
SIAM Journal on Applied Mathematics, 2015In [Comm. Appl. Math. Comput. Sci., 4 (2009), pp. 153-175], Barenblatt presents a model for partial laminarization and acceleration of shear flows by the presence of suspended particles of different sizes, and provides a formal asymptotic analysis of the resulting velocity equation. In the present paper we revisit the model.

Publisher Summary This chapter presents an overview of laminar flow. If the fully established flow in a duct is laminar; then the velocity distribution over a cross-section can be obtained quite easily, because at any given time only pressure and viscous forces act on a fluid particle.

Laminar Convection In Internal Flow
2021In Chap. 1, we have introduced the concept of convection through a phenomenological description by introducing h, the convection heat transfer coefficient. The heat transfer coefficient was introduced through the so-called “Newton’s law of cooling”. In many problems encountered in conduction heat transfer, we have made use of a suitable “h” value to ...
