In this device, the fluid occupies the space between two coaxial cylinders of radii a and b (> a); the outer cylinder is rotated with uniform angular velocity ω0, and the resultant torque transmitted to the inner stationary cylinder is measured.
where N is the set of radii.
We define a sequence of radii by setting and.
Consider a ring of radii and such that.
This is likely to be dispersed as very small particles of radii less than 1 μm.
The natural frequencies and mode shapes of the ring are calculated for various values of ratio of radii.
The annulus is assumed to be bounded by two cylinders of radii a and b, where (a < b).
To get a precise solution, this procedure was repeated several times by narrowing the range of radii of inner conductors.
The particles are attached to each other, otherwise distance between the particles is the sum of radii of particles.
This peak corresponds to the highest frequency of radii measured from local curvatures of undulations in the irregular garnets.
The conductivities of the samples are discussed in terms of radii and coordination numbers of the cations.
