MOTION OF PARTICLES IN A CENTRIFUGAL FIELD

In most practical cases where a particle is moving in a fluid under the action of a centrifugal…

Vertical motion (general case)

For the Stokes’ law regime equations 3.88, 3.89 and 3.90 are applicable. For the Newton’s law regime, R_/ρu2 is a constant and…

Motion of a sphere in the stokes’ law region

Under these conditions, from equation 3.5: if allowance is made for the added mass. In this particular case, the…

General equations of motion

The motion of a particle through a fluid may be traced because the value of the drag factor R_/ρu2…

Power-law fluids

Because most shear-thinning fluids, particularly polymer solutions and flocculated suspensions, have high apparent viscosities, even relatively coarse particles…

MOTION OF BUBBLES AND DROPS

The drag force acting on a gas bubble or a liquid droplet will not, in general, be the…

GAS–SOLIDS SYSTEMSGAS–SOLIDS SYSTEMS

General behaviour In general, the behaviour of gas-fluidised systems is considerably more complex than that of liquid-fluidised systems…

Terminal falling velocities

If a spherical particle is allowed to settle in a fluid under gravity, its velocity will increase until…

Motion of Particles in a Fluid

INTRODUCTION Processes for the separation of particles of various sizes and shapes often depend on the variation in…
