Free Stream Turbulence and the Critical Reynolds Number in a Duct

Transactions of the Canadian Society for Mechanical Engineering, 1973
The effect of the turbulence level in the free stream on transition in a duct was studied by extending a previous experimental investigation on the effect of turbulence for the developing flow through a circular duct. The result indicates that the flow is always laminar below a certain range of Reynolds number independent of the turbulence level ...

Pressure distributions on circular cylinders at critical Reynolds numbers

Journal of Fluid Mechanics, 1973
Measurements have been made of the mean and fluctuating pressure distributions on long circular cylinders, having smooth and rough surfaces, at Reynolds numbers of 1·11 × 105 and 2·35 × 105 in both uniform and turbulent streams. The presence of free-stream turbulence a t these Reynolds numbers was found to suppress coherent vortex shedding on the ...

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.

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 ...

Vehicles Drag Reduction With Control of Critical Reynolds Number

Journal of Fluids Engineering, 2013
Various vehicles have been designed as short blunt bodies. Drag coefficients of these bodies are high because adverse pressure gradients cause boundary layer separation from their surfaces, but a reduction of the size of separation zone allows for a substantial reduction of the body drag.

Insights on phase speed and the critical Reynolds number of falling films

Physical Review E
We revisit the studies of gravity-driven viscous falling films with and without imposed shear stress to provide new perspectives on phase speed and the critical Reynolds number for surface instability. We use the traditional long-wave expansion technique implemented for investigating the linear stability analysis [C. S. Yih, Phys.
