shape factor

[′shāp ‚fak·tər]
(electricity)
(electronics)
The ratio of the 60-decibel bandwidth of a bandpass filter to the 3-decibel bandwidth.
(fluid mechanics)
The quotient of the area of a sphere equivalent to the volume of a solid particle divided by the actual surface of the particle; used in calculations of gas flow through beds of granular solids.
(optics)
For a lens, the quantity (R2+ R1)/(R2-R1), where R1 and R2 are the radii of the first and second surface of the lens. Also known as Coddington shape factor.

Volume and surface area are linearly correlated, implying the correlation of the isoperimetric shape factors [f.
Among these design parameters, the shape factor and eccentric distance are the most important factors that influence the dimensions and performance of a Wankel compressor.
The strategies were used by developing a nanostructured co-polymerized coating, using high shape factor engineered (HSFE) clays that reduce permeation vie a tortuous path (12) as shown in Fig.
Shape factor of the ellipse obtained from central section is
0] is the dimensionless flow rate, A is the cross-sectional area, c is the shape factor corresponding to [n.
In this figure it can be observed that the greater the shape factor, the greater the forces required to carry out the process, so it means that as the dimensions of the workpiece increase, the necessary energy also increases for the same conditions of the process.
Interestingly, for the experimental geometry employed in this study, the shape factor as determined from our finite element model is close to 0.
Several parameters are considered in order to observe general trends on forces and contact pressure distributions: the friction between the die-workpiece interface ([mu]), the reduction in height (r) and the shape factor (h/b).
Two parameters, fractal dimension (roughness) and shape factor, were used to numerically characterize the graphite morphologies.
The system's measurement features include perimeter, area, distance, angle, slope, XY coordinates, compactness, feret diameter, shape factor, major/minor axes (length, slope, endpoint coordinates), center of mass (gray and binary), running tally, variable width line intensity, average intensity, and point intensity.
