Island wake impact on evaporation duct height and sea clutter in the lee of Kauai [PDF]

IGARSS 2001. Scanning the Present and Resolving the Future. Proceedings. IEEE 2001 International Geoscience and Remote Sensing Symposium (Cat. No.01CH37217), 2002
Perturbed flow over and around an island can produce leeside vortices and a long wake region of reduced wind speed and altered thermodynamic structure that impacts the evaporation duct height field and directional wave spectra, both of which impact radar sea clutter returns.

A Computational Approach for Biomimetic Design of Liver‐On‐A‐Chip

Advanced Intelligent Discovery, EarlyView.
A biomimetic liver‐on‐a‐chip with antiparallel perfusion was designed using COMSOL‐guided simulation to replicate hepatic acinus transport. Full‐scale modelling revealed diffusion‐dominated, length‐dependent nutrient gradients and low‐shear conditions.
