Bubble rising under the in?uence of gravitational force is one of the most common gas–liquid flow phenomena. Understanding the dynamic interaction between the phases is an important key for the design and operation of industrial applications. A particular instance of this situation occurs in gas...
Learn what is centripetal force and see how to calculate it using the centripetal force equation, and study centripetal force examples with...
The Ergun equation was derived using the packed-bed pressure drop data, whereas the Wen and Yu model was formulated based on the homogeneous expansion of fluidized beds. This drag model was recommended for describing dense fluidized beds. The interphase momentum transfer force Ff is expressed as ...
The most common examples of forces are gravitational and normal forces. Gravitational force is a non-contact force and is an attractive force between two objects with mass. For example, Earth exerts a gravitational force on the Moon. Normal force is a force that acts perpendicular to the surfac...
However in a stationary fluid the mean pressure gradient is zero and only matched by gravitational forces which have been ignored, so we can specify ∂(po+p′)/∂xi = ∂p′/∂xi, which is also linearly dependent on small quantities. The term ∂(vivj)/∂xj is nonlinear and ...
The increased kinetic energy comes from the net work done on the fluid to push it into the channel and the work done on the fluid by the gravitational force, if the fluid changes vertical position. Recall the work-energy theorem, Wnet=12mv2−12mv02Wnet=12mv2−12mv02. There is a ...
(1) and (2) are two forms of the Bernoulli Equation for a steady state in-compressible flow. If we assume that the gravitational body force is negligible - the elevation is small - then the Bernoulli equation can be modified top = p1 + ρ v12 / 2 = p2+ρ v22 / 2 - ploss ...
