The Dean equations extended to a helical pipe flow

Journal of Fluid Mechanics, 1989
In this paper the Dean (1928) equations are extended to the case of a helical pipe flow, and it is shown that they depend not only on the Dean number K but also on a new parameter λ/[Rscr ] where λ is the ratio of the torsion τ to the curvature κ of the pipe axis and [Rscr ] the Reynolds number referred in the usual way to the pipe radius a and ...

Tollmien—Schlichting wave/Dean vortex interactions in curved channel flow

Journal of Fluid Mechanics, 1992
Evidence from direct numerical simulations and from a recent weakly nonlinear theory is presented which shows that the weakly nonlinear results of Daudpota, Hall & Zang (1988) make incorrect predictions for the influence of the Tollmien–Schlichting wave on the Dean vortex.

Study of flow and mixing of dean flow and dean instability in inertial microfluidics

Inertial microfluidics is an emerging field deviates from the conventional microfluidics due to its unqiueness in consideration of inertia. Dean flow and Dean instability play an important role in inertial microfluidics, with a wide application in mixing and sorting. However, most studies are limited to Dean flow on the microscale.

Spatial Direct Numerical Simulations of Transition in Rotating Dean Flow

1998
The investigation of flows in situations where large scale streamwise vortices appear, such as in curved and/or rotating boundary layers and channels, is a task of interest in practical problems (i.e. water turbines) and at the same time it presents a fundamental appeal for its role of model configuration for the comprehension of the processes leading ...
