Fluid flow and heat transfer in bending channels are topics of much research interest because of increasing demand in various fields, particularly in the medical and industrial arenas. This paper presents a numerical study of fluid flow and heat transfer in a bending channel with a square cross section.

Effects of Dean vortex pairs on surface heat transfer in curved channel flow
International Journal of Heat and Mass Transfer, 1996Heat transfer in transitional curved channel flow is investigated over a range of Dean numbers less than 300. The channel aspect ratio is 40, radius ratio is 0.979 and the ratio of boundary layer thickness to channel width is 0.011. Forced convection Nusselt numbers show the influences of Dean vortex pairs and other transitional phenomena.

Dean vortex stability using magnetic resonance flow imaging and numerical analysis
AICHE Journal, 2001AbstractMagnetic resonance flow imaging using flow encoding with spin warp imaging was used in three dimensions to measure velocity profiles and the dynamic behavior of centrifugally‐induced (Dean) vortices in curved tube flow. Experimental measurements were compared with numerical simulations obtained from the solution of Navier‐Stokes and continuity ...

Abstract A novel UV-C irradiation device in laboratory scale was tested for its potential to inactivate bacteria in naturally cloudy apple juice. In this device, liquid flows through a helically wound tubing wrapped around a quartz glass tube containing a 9 W UV lamp with an irradiation intensity of 60 W/m2 at 254 nm.

Journal of Heat Transfer, 2017 The efficiency of conventional heat exchangers is restricted by many factors, such as effectiveness of convective heat transfer and the cost of their operation. The current research deals with these issues by developing a novel method for building a lower-cost yet more efficient heat sink.

Viscosity effects on Dean vortex membrane microfiltration
AIChE Journal, 1999AbstractThe influence of changing viscosity by adding polyethylene glycol (PEG) during microfiltration of silica suspensions in the presence and absence of Dean vortices was determined. A new microfiltration membrane module design containing helically wound hollow fibers (with Dean vortices) was compared with a standard commercial cross‐flow module ...

Tollmien—Schlichting wave/Dean vortex interactions in curved channel flow
Journal of Fluid Mechanics, 1992Evidence 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.
