Continuous Reynolds number effect analysis of the influence of vortex generator on the aerodynamic performance of airfoil [PDF]
In order to effectively improve the power generation efficiency of large wind turbines, studies on the optimization measures for the aerodynamic performance of wind turbine airfoils were conducted. Wind tunnel experiments were conducted to systematically

Comparison of a grid-based CFD method and vortex dynamics predictions of low Reynolds number cylinder flow [PDF]
Computational fluid dynamics models range from the finite difference type grid-based method to the Lagrangian style vortex cloud simulation technique for solving the Navier-Stokes equations.

Mechanism of Drag Reduction by Dimple Structures on a Sphere
The purpose of the present study is to clarify the mechanism of drag reduction for a sphere with arc type dimples. The sphere has 328 dimples of different depths uniformly distributed on its surface.

The critical Reynolds number of a laminar mixing layer
It has hitherto been widely considered that a mixing layer is unstable at all Reynolds numbers. However this is untenable from energy considerations, which demand that there must exist a non-zero Reynolds number below which disturbances cannot extract energy from the mean flow.

Reynolds number of transition and self-organized criticality of strong turbulence [PDF]
A turbulent flow is characterized by velocity fluctuations excited in an extremely broad interval of wave numbers k>Λf, where Λf is a relatively small set of the wave vectors where energy is pumped into fluid by external forces.

Critical Reynolds Number Estimates by Thermo-Dynamic (Stochastic) Methods
Methods based on fundamental thermodynamic principles and the notion of statistical probability have been used to estimate the point of instability and the lower critical Reynolds number for a round pipe and an infinite channel.
