Natural Laminar Flow and Laminar Flow Control
1992The present volume discusses the development history and basic concepts of laminar flow control, laminar flow flight experiments, subsonic laminar-flow airfoils, and a design philosophy for long-range laminar flow-control commercial transports with advanced supercritical airfoils.

Laminar Flow in Tubes with Constriction
The Physics of Fluids, 1972To understand the abnormal flow conditions caused by the presence of stenoses in arteries, an analytical solution is obtained for the steady laminar flow of an incompressible Newtonian fluid in an axisymmetric conduit with irregular surface where the spread of the surface roughness is large compared with the mean radius of the conduit.

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.

On Autoignition of Co-Flow Laminar Jets
SIAM Journal on Applied Mathematics, 2016The authors analyze a mathematical model accounting for the thermal runaway followed by ignition in laminar jets. After a change of variables and unknowns through an adimensionalization process, they consider the system of parabolic equations \(\theta _{\zeta }=\theta _{\xi \xi }+\frac{1}{\xi } \theta _{\xi }\) for \((\xi ,\zeta )\in (0,\lambda )\times

Laminar Flow in a Meandering Channel
SIAM Journal on Applied Mathematics, 1983The author has studied the laminar flow in a meandering channel on the assumption that the curvature of the centreline is both small and slowly varying. Solution is obtained up to fourth approximation for a general shape of centerline using only elementary functions.

Journal of Applied Mechanics, 1954
Abstract The problem of the decay of a rotationally symmetric steady swirl superimposed on Poiseuille flow in a round pipe was investigated theoretically and experimentally. The object was to determine the degree to which the rate of decay of the swirl as predicted by a linearized theory agreed with measured rates of decay at flow ...

Laminar Flow Infrared Spectroelectrochemistry
Analytical ChemistryIn this work, we advance lab-on-chip electrochemistry and spectroscopy by combining these capabilities onto a single platform, thereby achieving mid-infrared spectroelectrochemistry (SEC) for the first time. The key feature of this technique is the use of deterministic laminar flow patterns to precisely transport a reacted solution from upstream ...

AbstractSteady laminar flow in a curved pipe of circular cross section is investigated. It is assumed that the flow consists of a frictionless central core surrounded by a boundary layer. A formula for the friction factor of a curved pipe is derived, and the discharge coefficient for a 360‐deg elbow flowmeter is discussed.

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.
