Fish fins and fast-starts: Multi-level analyses reveal functional variation within median fins of bluegill sunfish.
Fins act as control surfaces by which fish can generate and react to hydrodynamic forces during a variety of locomotor behaviors. Within the ray-finned fish, the unique segmented, bilaminar design of their fin rays, for which they are named, provide the fish with the ability to independently …

Thermo-hydraulic study of inclined louvered fins
… the air side. To increase the heat transfer rate fins are added on the airside which increase the surface area. Over the past decades a considerable amount of research has been performed to improve the performance of fin-andtube heat exchangers: e.g. transfer the same amount of heat with a smaller …

Analysis of Mo sidewall ohmic contacts to InGaAs fins
As transistor size is scaled down, the performance is degraded and many problems, so called shortchannel effects, arise. To address this problem, a vertical transistor structure such as vertical nanowire is suggested. In a vertical nanowire field-effect-transistor, the Ohmic contact at the top of …

Thermal and Hydraulic Characterization of Hook-Shaped Fins and Dimples
… pressure drop of GRIPMetal arrays – hook-shaped fins with dimples – under varying tip clearances and attack angles. Experiments with water-cooled GRIPMetal surfaces explored Reynolds numbers (Re) from 600 to 12,000, while simulations examined attack angles (α) from 0° to 90°. Results showed that …
