Flow Velocity Coefficient Research on the Coexistence of Pipe Flow and Flow around Pipe
Advanced Materials Research, 2011Based on Darcy - Weisbach route losses equation, this test is focused on the mixed-flow problems at low speed in big flow field, designing the experiment scheme, introducing its principle, and setting up the test rig. According to the test result data, we put forward the definition of flow speed coefficient and draw its curves, and described some ...

On Viscous Flow in a Pipe with Constrictions
Mathematical Proceedings of the Cambridge Philosophical Society, 1962ABSTRACTTwo methods of solution are given for the flow of a viscous liquid in a circular pipe whose radius has a slight sinusoidal variation. Numerical examples are given, and some related problems are briefly discussed.

Viscous Flows in Corrugated Pipes
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1995Analytical solutions describing Stokes flows in a corrugated pipe of a special form and in annular region between such two pipes are obtained using epitrochoid and hypotrochoid conformal mappings. There are two parameters in the mappings: one is the amplitude of the corrugation, and the other is related to the wavelength of the corrugation.

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.

Pipe Flow of Plastic Materials
Journal of Applied Mechanics, 1980Plastic materials behave as both solids and fluids. When forced to move in a pipe, they flow as a solid plug with a slipping boundary. Depending on the cross-sectional shape of the pipe, the slipping boundary may not coincide with the inner boundary of the pipe. When such is the situation, there exist dead regions in the flow.

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 ...
