Convection and convective‐organization in hothouse climates

G Dagan, JT Seeley, N Steiger - Journal of Advances in …, 2023 - Wiley Online Library
In a “hothouse” climate, warm temperatures lead to a high tropospheric water vapor
concentration. Sufficiently high water vapor levels lead to the closing of the water vapor …

Boundary-layer disruption and heat-transfer enhancement in convection turbulence by oscillating deformations of boundary

L Yuan, S Zou, Y Yang, S Chen - Physical Review Letters, 2023 - APS
In this Letter, we propose a novel strategy for significantly enhancing the heat transfer in
convection turbulence. By introducing a boundary deformation of the standing-wave type …
