A Review of Airside Heat Transfer Augmentation with Vortex Generators on Heat Transfer Surface
Energies, 2018 Heat exchanger performance can be improved via the introduction of vortex generators to the airside surface, based on the mechanism that the generated longitudinal vortices can disrupt the boundary layer growth, increase the turbulence intensity and ...

Heat transfer enhancement in a spiral plate heat exchanger model using continuous rods [PDF]
Journal of Heat and Mass Transfer Research, 2020 This study presents an innovative and simple way to increase the rate of heat transfer in a spiral plate heat exchanger model. Several circular cross-section rods, as continuous vortex generators, have been inserted within the spiral plate heat exchanger

Generalized Newton’s rings with vortex beams
Optics Express, 2022 The Newton’s rings are interference patterns with concentric rings, and Newton’s rings experiment is one of the most famous classic optics experiments. Here, we show that if we use a vortex beam, we can obtain generalized Newton’s rings. Unlike traditional Newton’s rings, the generalized ones are no longer concentric rings but spiral arms, and fork ...
