Coriolis effect on water waves

Waves, Coriolis Force and the Dynamo Effect

Dynamo activity caused by waves in a rotating magneto-plasma is investigated. In astrophysical environments such as accretion disks and at sufficiently small spatial scales, the Hall effect is likely to play an important role. It is shown that a combination of the Coriolis force and Hall effect can produce a finite α-effect by generating net helicity in the small scales. The shear/ion-cyclotron...

The Coriolis Effect on Vesta’s Southern Basin Rheasilvia

Vesta’s giant south polar impact basin Rheasilvia exhibits a spiral deformation pattern. We tested whether or not the Coriolis force has caused the curved features of the pattern. For this we mapped the curved features and calculated the velocities along them using the Coriolis theory. The resulting velocities indicate that the Coriolis force is a candidate to have caused the spiral deformation...

Polymerization of Silica in Water-Effect of Ultrasonic Waves on Coagulation and Sedimentation

Polymerization rates of silica at various concentrations and pHs have been studied via nephelometry. The ability and potency of ultrasonic radiation on the coagulation process in aqueous samples with and without silica colloidal particles have been extensively investigated. Factors affecting the rate and filtration volume such as silica concentration, time of radiation, temperature, and fre...

Elliminating the Coriolis Effect in Liquid Mirrors

If uncorrected, the Coriolis force due to the rotation of the Earth causes significant aberration of images produced by large liquid-mirror telescopes. We show that this problem can be eliminated by a fixed compensating tilt of the liquidmirror rotation axis. The required tilt angle, which is a function of latitude and mirror rotation rate, is of order 10 arcsec for current telescopes. This res...
