Dynamic vortex characteristics and their contribution to heat transfer enhancement in the channel of a serrated finned tube heat exchanger

Case Studies in Thermal Engineering
The dynamic vortex characteristics and thermal-hydraulic performance of a serrated finned tube heat exchanger were numerically analyzed under varying Reynolds numbers (Re = 10,000–60,000), fin spacing (Sf = 3.63–6.76 mm), and fin height (hf = 10.7–14.7 ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Reduced-order modelling of vortex-induced vibration of catenary riser [PDF]

, 2009
A new reduced-order model capable of analyzing the vortex-induced vibration of catenary riser in the ocean current has been developed. This semi analytical-numerical approach is versatile and allows for a significant reduction in computational effort for

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions

Advanced Materials, EarlyView.
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.
