Chiral symmetry breaking and entropy production in Dean vortices
Physics of Fluids, 2023 In toroidal pipes, the secondary flow in cross section is a mirror symmetric pair of counter-rotating axially oriented Dean vortices. This mirror symmetry is broken in helical pipes. We investigate in detail the mirror symmetry breaking in these secondary flows in going from toroidal to helical geometries.

Effects of inlet junctions on horizontally stratified flows
AIP Advances, 2023 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

Impact of Dean Vortices on the Integrity Testing of a Continuous Viral Inactivation Reactor [PDF]
Biotechnology Journal, 2018 We propose a standard protocol for integrity testing the residence‐time distribution (RTD) in a “Jig in a Box” design (JIB)—a previously described tortuous‐path, tubular, low‐pH, continuous viral inactivation reactor, ensuring that biopharmaceutical products will be incubated for the required minimum residence time, tmin .
