Coriolis effect

Princen and co-workers have treated the more general case where w is too small or y too large to give a cylindrical profile [86] (see also Refs. 87 and 88). In such cases, however, a correction may be needed for buoyancy and Coriolis effects [89] it is best to work under conditions such that Eq. 11-35 applies. The method has been used successfully for the measurement of interfacial tensions of 0.001 dyn/cm or lower [90, 91]. [Pg.31]

Its equations account for advection, Coriolis effects, turbulent heat, momentum, moisture iran.sport, and viscosity. The system treats diurnaliy varying winds such as the land-sea breeze and... [Pg.355]

The flames in the rotating vessels represent an interesting case, where the Coriolis effects are strong. However, further studies of the effects on flame propagation and structure are required. [Pg.135]

True challenges are flows with instabilities and, in particular, the turbulent flows where Coriolis effects change the flame perturbation geometry. [Pg.135]

Coriolis effect The apparent force acting on moving particles that results from Earth s rotation. The Coriolis Effect causes freely moving bodies to be deflected to the tight of their direction of motion in the northern hemisphere and to the left in the southern hemisphere. [Pg.871]

Geostrophic current The advection of water resulting from the balance between gravity, wind stress, and the Coriolis Effect. [Pg.875]

Devices using the Coriolis effect are available for moderate pressures, up to 400 bar. For high flow-rates the the maximum pressure is approx. 250 bar [11]. The advantage of these instruments is their wide range of flow. [Pg.239]

Three forces combine to drive the GHCB. The first is the Coriolis effect, which is caused by the rotation of the globe and results in a faster movement of the ocean s surface near the equator. The second is the level of the Pacific... [Pg.27]

There are many other flow measurement devices including Onlicc/Venturi meters, turbine meters, and more sophisticated instruments using ultrasonic, magnetic, and Coriolis effect techniques. Orifice/Venturi type meters have a restriction causing a pressure drop related to the flow rate of liquid. Such meters are popular because of their low cost however, their accuracy can be compromised by upstream elbows and valves. Turbine meters are designed so that rotation speed varies linearly with the... [Pg.196]

The discovery of the Coriolis effect resulted from work done by Caspar Gustav de Coriolis (1792-1843) at the behest of Napoleon, who wanted to know why his cannon balls never went straight. There is no historical record to indicate that Coriolis cast any light on Napoleon s problem but, as often happens in research, unexpected findings can stimulate curiosity and lead to other useful outcomes—as Pasteur once said, Chance only visits the prepared mind. ... [Pg.197]

We first look at the form of the calculations for the A -doubling parameters, p and q, which are a measure of the mixing of the 2 ft state with the 2 + and 2 S states brought about by the combined effects of spin-orbit coupling and Coriolis effects. Specifically we showed in chapter 8 the results [190] first obtained by Mulliken and Christy ... [Pg.807]

Referring to Table 2.2, we see that for case (i), typical small to medium scale urban areas, buoyancy and Coriolis effects are negligible and F > 1, and LR > Lc. For case... [Pg.33]

Boundary Layer (Outer) Scale Lo Flow over obstacles/buildings. Significant orographic / Coriolis effects (but affected by smaller scales). Surface influences and pollutants mixed through boundary layer. L0 for large urban areas (x Lo) h... [Pg.34]

Fig. 3.3 (a) Generalized atmospheric pressure, wind and precipitation patterns on an ocean-covered Earth (n. b. sphere is elongated to aid clarity of wind patterns), (b) Idealized major oceanic surface current systems in the Pacific and Atlantic oceans. The Coriolis effect is responsible for disruption of the meridional circulation cells between 30 and 60° in (a). [Pg.76]

The movement of water and air masses over the Earth is subject to the Coriolis effect, which results from the fact that the velocity of the Earth s surface in the direction of spin (eastwards) is greatest at the equator and decreases to zero at the poles. Consequently, as water moves away from the equator at the western margins of the main oceans (where it is piled up by the action of the Trade Winds), it moves progressively faster than the Earth s surface in an easterly direction. In the northern hemisphere its motion is turned progressively clockwise, while in the south-... [Pg.76]

The principle of operation of transducers is based on the conservation of either linear (i.e., Coriolis effect) or angular momentum, making a transducer well suited for micromachined rate-sensing gyros. One or more linearly or rotationally vibrating probe masses are required, for which the input motion stimulus and the output signal can be accomplished by various physical effects (electrostatic, electromagnetic, piezoresistive, etc.). Usually the drive motion is resonant, so the detection motion can also be resonant or the two natural frequencies are separated by a certain frequency shift. Drive and detection motion can be excited by inplane motions or by a mixture of in-plane and out-of-plane motions. [Pg.45]

The Coriolis meter is commonly used to measure liquid flow rates. The coriolis meter utilizes the coriolis effect to directly measure the mass flow rate of liquids. The meter is equipped with a specially shaped vibrating tube through with the liquid flows. When a fluid flows through the tube it alters the manner in which the tube vibrates. The mass flow rate of the fluid is then... [Pg.389]

Coriolis effect - The deviation from simple trajectories when a mechanical system is described in a rotating coordinate system. It affects the motion of projectiles on the earth and in molecular spectroscopy leads to an important interaction between the rotational and vibrational motions. The effect may be described by an additional term in the equations of motion, called the Coriolis force. [Pg.100]
