Multivortex micromixing: novel techniques using Dean flows for passive microfluidic mixing [PDF]
, 2007 Mixing of fluids at the microscale poses a variety of challenges, many of which arise from the fact that molecular diffusion is the dominant transport mechanism in the laminar flow regime. The unfavorable combination of low Reynolds numbers and high P

Large-eddy simulation of turbulent duct flow: heating and curvature effects
, 2004 Large eddy simulations of the turbulent gas flow within ducts of square cross-section are performed. The spatial development of turbulent flow inside a heated straight duct is first considered with a higher temperature suddenly imposed at one of the duct

Effects of centrifugal instabilities on laminar/turbulent transition in curved channels with 40 to 1 aspect ratios [PDF]
, 1991 Dean vortices in curved channels with 40 to 1 aspect ratios were measured and studied over the range of Dean numbers from 50 to 450. At low Dean numbers (50) the flow is fully laminar.

Numerical simulations of vortices near free and solid surfaces
, 2007 The interaction of vortices passing near free and solid surfaces has been examined using direct numerical simulation (DNS). A computer code was developed which solves the unsteady, three-dimensional Navier-Stokes equations for incompressible flow.

Inertial micromixing in curved serpentine micromixers with different curve angles
, 2019 Micromixers are of considerable significance in many microfluidics system applications, from chemical reactions to biological analysis processes. Passive micromixers, which rely solely on their geometry, have the advantages of low cost and a less-complex

Asymmetry Propagation in a Pipe Flow Downstream of a 90° Sharp Elbow Bend
Applied SciencesPipe bends disrupt the flow, resulting in an asymmetric velocity field across the pipe diameter (D). We examined the recovery length required for the flow to return to a symmetric velocity profile downstream of a sharp elbow. The wall-resolved Large Eddy

Entropic Evaluation of Dean Flow Micromixers
, 2013 In the present work, we investigate computationally, using COMSOL Multiphysics and its CFD and Chemical Species Transport modules, the use of spiral channels at Reynolds numbers from 25 to 900, as mixing structures.

Analysis and Control of Complex Flows in U-Bends using Computational Fluid Dynamics
, 2014 Analysis and control of flow structure in U-bends are crucial since U-bends are used in many different engineering applications. As a flow parameter in U-bends, the ratio of inertial and centrifugal forces to viscous forces is called as Dean number.
