Laminar-turbulent transition in Taylor-Dean flow
An experimental study is reported of flows produced in a moderate Taylor-Couette system, Γ ≈ 15, closed or azimuthally opened. In the last case, the flow is bounded by θ = 0 and (2π − θ1) where θ1 = 30° represents the region cut-off by a diaphragm.

Experimental Study of Heat Transfer Coefficients of Shell and Helically Coiled Tube Heat Exchangers [PDF]
This work presents an experimental study of the heat transfer coefficients of shell and helically coiled tube heat exchangers. Three heat exchangers with different coil pitches were tested for both parallel-flow and counter-flow arrangement.

The Separation of Microalgae Using Dean Flow in a Spiral Microfluidic Device
A cell-in-droplet encapsulation using Dean flow in a spiral microfluidic device was applied to separate microalgae. In recent years, researchers have been interested in separating micro particles using microfluidic chips because of its great advantages ...

Effects of inlet junctions on horizontally stratified flows
Horizontally stratified flows can be seen in a wide variety of micro-scale engineering problems. Recent studies have shown that diffusion at the interface between two liquids leads to a lateral flow, causing the fluid to rotate around the central axis of

The influence of secondary flow structures in a turbocharger turbine housing in steady state and pulsating flow conditions [PDF]
This paper presents a computational investigation into the effect of volute secondary flow structures on turbine inlet flow conditions. The steady state results show Dean type vortices exist early in the volute.
