Streamwise oscillations of cylinders near the critical Reynolds number

Journal of Fluids and Structures, 1987
The purpose of the research reported here is to attempt to clarify the conditions under which in-line oscillations of a circular cylinder occur, and to establish the oscillation characteristics. A mathematical model has been developed which attempts to represent a cylinder vibrating in the streamwise direction.

On the Lower Critical Reynolds Number for Flow in a Circular Pipe

Fluid Dynamics, 2003
Flow in a circular pipe is investigated experimentally at Reynolds numbers higher than that at which the resistance coefficients calculated from the Blasius formula for laminar flow and from the Prandtl formula for turbulent flow are equal. The corresponding Reynolds number based on the mean-flow velocity and the pipe diameter is about 1000.

Critical Reynolds Number For Orifice And Nozzle Flows In Pipes

Journal of Hydraulic Research, 1977
The critical Reynolds number at which the flow downstream of an orifice or nozzle in a pipe becomes turbulent is an important parameter as it is the demarcating point between purely laminar flow and relaminarising flow. The value of the critical Reynolds number is estimated for sharp-edged orifices, quadrant-edged orifices and long radius nozzles from ...

Reynolds number criticality in dynamic tests

16th Aerospace Sciences Meeting, 1978
To extrapolate from subscale wind tunnel tests to full-scale flight is a well-recognized problem. It becomes especially critical for present day high performance missiles and aircraft which operate at high angles of attack where separated flow effects often dominate the vehicle aerodynamics.

Critical Reynolds Number and Flow Permeability

American Journal of Physics, 1954
Liquids of three different viscosities have been used in determining the flow permeability of fourteen media composed of spherical glass beads. Darcy's law has been found to hold for a Reynolds number up to 75. Three methods are given for determining the average bead diameters.
