Shape factor for cylinder
Shape factors are dimensionless quantities used in image analysis and microscopy that numerically describe the shape of a particle, independent of its size. Shape factors are calculated from measured dimensions, such as diameter, chord lengths, area, perimeter, centroid, moments, etc. The dimensions of the particles are usually measured from two-dimensional cross-sections or projections, as in a microscope field, but shape factors also apply to three-dimensional objects… WebbThe view factor 12 is the fraction of energy exiting an isothermal, opaque, and diffuse surface 1 (by F emission or reflection), that directly impinges on surface 2 (to be …
