Mass wasting and the Coriolis effect on asteroid Vesta
This work investigates the influence of the Coriolis force on mass motion related to the Rheasilvia impact basin on asteroid (4) Vesta's southern hemisphere. The giant basin is 500km in diameter, with a centre which nearly coincides with the rotation axis of Vesta. The Rheasilvia basin partially …

The feasibility of micromachined dynamic resonant beam coriolis true mass flow meter
… sensing and flow measurement based on the Coriolis effect. Coriolis sensing is particularly attractive since, unlike most other methods which provide volumetric flow information, Coriolis sensing is capable of providing a direct, true mass flow measurement. Because of this advantage, …

Artificial gravity : changing the intensity of coriolis cross-coupled stimulus with head-angle
… head-movements in a rotating environment create Coriolis cross-coupled stimuli that introduce problematic vestibular responses. Earlier studies have shown that it is possible to achieve at least partial adaptation to these stimuli, and that side-effects diminish by the end of the training. This …

A model of the equatorial deep jets and the role of the horizontal Coriolis parameter
… to the study of the role of the horizontal Coriolis parameter. Most existing analytical models interpret the equatorial deep jets as either low frequency, long Rossby waves or stationary,long Kelvin waves generated at or near the ocean surface. These models are unable to answer the question …

Quantifying the Cognitive, Symptomatic and Neuroendocrine Impact of the Coriolis Illusion; A Countermeasure for Motion Sickness
… neuroendocrine and subjective symptoms of the Coriolis illusion, induced by a spatial disorientation flight training device. Also, the research examined the effectiveness of a mild, ground-based countermeasure, similar to the Coriolis illusion, in reducing the occurrence and severity of …

Effect Of Coriolis And Centrifugal Forces On Turbulence And Transport At High Rotation And Buoyancy Numbers
… Reynolds stresses and transport are affected by Coriolis and buoyancy/centrifugal forces caused by high levels of Ro and DR. Variations of flow total pressure along the rotating channel are also predicted. The results obtained are explained in view of physical interpretation of Coriolis and …

Large Eddy Simulations of Flow and Heat Transfer in the Developing and 180° Bend Regions of Ribbed Gas Turbine Blade Internal Cooling Ducts with Rotation - Effect of Coriolis and Centrifugal Buoyancy Forces
… all comparisons. In the developing flow region, Coriolis effects are found to destabilize turbulence and increase heat transfer along the trailing wall (pressure side), while decreasing leading wall heat transfer by stabilizing turbulence. Coriolis forces improve flow turning in the 180° bend by …
