The effect of operating conditions (rotation rate, vessel fill percentage and total number of revolutions) was examined.
This expression, upon application of the thin-layer approximation, is reduced to give an explicit relationship between the solids exchange coefficient and drum operating parameters such as rotational speed and fill percentage, as well as the bed material rheological properties.
The dimensionless groups investigated include the drum length-to-diameter ratio, rotational Froude number, fill percentage, particle-to-drum diameter ratio, particle restitution coefficient, and the relative drum wall roughness.
After 1, 4 and 9 weeks of submerged healing, dissected blocks were processed for immunohistochemical (osteocalcin) and histomorphometrical analysis (residual defect length, new bone-implant contact, area of new bone fill, percentage of osseointegrated bone-graft particles).
It is shown that the Froude number, particle-to-drum diameter ratio, drum fill percentage, and particle restitution coefficient can be combined to give a single dimensionless parameter if drums are operated in a rolling mode and the Froude number is greater than 0.003.
The derived dimensionless groups include Froude number, pseudo-Reynolds number, pseudo-Euler number, drum geometric ratios, drum inclination, drum fill percentage, size distribution of particles, and physical properties of the particles and drum wall such as restitution coefficient and elasticity modulus.
The red blood cell (RBC) filling percentage is calculated an estimate for microvascular perfusion.
The differences in spikelet filling percentage between hybrid rice and inbred cultivars were small or inconsistent.
Both spikelet filling percentage and grain weight were lower in Changsha than in Xingyi by approximately 8%%.
Pore filling percentage is approximately 100% for Ni NWs grown in a NpAT by potentiostatic deposition (Figure 2b,c).
According to the grain size statistics, a mean value of 20 nm was obtained with a filling percentage of 43%.
