This in turn reduces the adhesion forces between particles and the substrate causing the meniscus capillary forces to effectively remove the largest diamond crystals from the PAAO membrane with a net force [F.
Hence, it remained the vertical flow of infiltration depth due to capillary force and gravity force (one-dimensional infiltration depth) as stated by Equation 4.
After conventional water flooding process the residual oil in the reservoir remains as a discontinuous phase in the form of oil drops trapped by capillary forces and is likely to be around 70% of the original oil in place [1].
SEM images demonstrated that van der Waals attraction force alone can compact a latex coating under conditions devoid of surface tension and capillary forces, which means capillary forces are not necessary for latex film formtion.
The predominant forces are the gravitational and capillary forces.
They've identified several areas on engines where a capillary force vaporizer could be used to mete out fuel or clean up exhausts.
The centrifugal force generated in the CD-player-like instrument overcomes, depending on the rotation speed, the capillary forces in the fluidic network.
From the Taylor's works, the deformation and break up process of the droplet is related to the ratio of the viscous force to capillary force, which is expressed in the capillary number shown in Eq.
Small capillary gaps have a strong tendency to hold the solder because the capillary force in these cases is strong.
The good coincidence between the hydrophobizing of the exposed resist by surfactant adsorption and the pattern collapse reduction demonstrates that: (i) the hydrophobizing of the resist causes a decrease of the capillary force and thus a pattern collapse reduction; and (ii) the .
