Impact of Wind‐Wave Coupling on Turbulence and Air‐Sea Fluxes: Insights From Direct Numerical Simulations

open access: yesGeophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Accurate prediction of air‐sea fluxes hinges on a deep understanding of wind‐wave interactions, yet feedback mechanisms involving surface waves and wind are not fully understood. This paper investigates the effect of two‐way coupling between wind and waves on wind turbulence through direct numerical simulation of air‐water two‐phase flows ...

An experimental investigation on the airside performance of fin-and-tube heat exchangers having corrugated louver fins - Part II; wet surface

open access: yesJournal of Thermal Science and Technology, 2020
In this study, two kinds of corrugated louver fin-and-tube heat exchangers – one having one corrugation per row and the other having two corrugations per row – were tested under wet condition, and the results were compared with those of the standard ...

Wave Glider‐Based Measurements and Corrections of Near‐Surface pCO2 Gradients in the Coastal Ocean

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 7, July 2025.
Abstract Carbonate system dynamics are highly variable in coastal and shelf regions, and poor spatiotemporal measurement resolution leads to inadequate constraints for global carbon sequestration estimates. Additionally, conventional pCO2 measurement‐based flux calculations require an assumption of homogeneity in near‐surface waters, excluding effects ...

An experimental investigation on the airside performance of fin-and-tube heat exchangers having corrugated louver fins - Part I; dry surface

open access: yesJournal of Thermal Science and Technology, 2020
Corrugated louver fin, which has louvers on wavy surface, may be a promising mean to augment the air-side heat transfer of fin-and-tube heat exchangers. However, only limited prior studies are available.

Balancing Variety and Quality: Examining the Impact of Benefit‐Linked Cross‐Subsidization on Multisided Platforms

open access: yesJournal of Management Studies, Volume 62, Issue 4, Page 1717-1746, June 2025.
Abstract Multisided platforms face a fundamental trade‐off: should they ease entry for a larger number of providers of complementary products or services (complementors) to join the platform and benefit from cross‐side network externalities, or should they limit entry to maintain complementors’ incentives to provide high‐quality offerings?
