And the surface conditions, especially the wettability, also greatly affect the movement of the impacting droplet [1].
The model suggested that a hysteretic tension, γ, should be introduced to guarantee mechanical equilibrium at the contact line on a rough solid surface shown in Fig. 2.
According to the forces balance on the contact point, advancing and receding dynamic contact angles are: ( 7(4) (8 )(5) where , which is related to the effect of the solid surface properties.
The dimensionless spread factor, the dimensionless height of droplet and the droplet shapes were compared with the experimental data.
In present theoretical model, a correction factor is used to estimate the wetting effect.

Then the total mass flow through a face is computed by adding the groove and land mass flows averaged by the appropriate weight factor, ψη and (1-ψη), respectively.
The same principle is also used in groove/dam boundary through another weight factor, ψξ, in Figure 4(b).
We can see that the using JFO model increases cavitaiton area, at the same time, cavitation model affects the calculated positive pressure distribution.
Thus, we can conclude that cavitation occurrence significantly affects the sealing performances.
The effects of cavity fluctuation on the elastic and damping properties of journal bearings[J].

Cadmium (Cd), lead (Pb), etc. absorption and accumulation of plants are affected by many factors, such as soil texture, pH value, organic matter, coexisting elements [2-5], etc.
Basic physical and chemical properties of the soil are shown in Table 1.
Basic physical and chemical properties of soil are measured by conventional analysis of soil agrochemistry [6].
Cd and Zn belong to the same element family, which have similar chemical properties.
Such an interaction is one of main factors that affect Cd absorption and accumulation of plants.

The mechanical behavior of the shock absorber shows geometry nonlinearities, material nonlinearities , load nonlinearities and contact nonlinearities[1-2]. 1.2 FEM Model 1.2.1 Material Properties Compared with a tire, the shock absorber makes a very big difference.
Fig.1 Increment of diameter with respect to a cord angle Fig.2 Increment of radius with respect to a cord modulus (2) Effects of Young’s Modulus of the fabric-reinforced rubber on the outer radius The Young’s Modulus of the fabric-reinforced rubber is also quite an important factor except that the cord angle strongly affects the performance of the shock absorber.
The analysis results demonstrate that the cord angle and the fabric elastic modulus have a great effect on the deformation, and consequently those factors will also influence the static characteristics of the shock absorber.

This approach allows taking into account all factors of possible accident development.
The most common are express methods that take into account only the most important factors with a certain step of parameter change [13].
At the same time, the intensity of sorption depends not only on the surrounding conditions, but also on the surface properties of the liquid and the physical and chemical properties of HCM [33].
The use of mechanical lifts can increase the height of the sorbent jet supply up to 50 m.
Kozlovskaya, A study of significant factors affecting the quality of water in the Oskil River (Ukraine).

As such alloys may exhibit the rheological behaviour required for semisolid forming and the excellent final mechanical properties of Al-Zn alloys, we investigated the thermodynamic aspects of the solid-liquid transition of Al-5.5wt%Si-5wt%Zn alloy, the morphological stability of this alloy in the semisolid temperature range and the corresponding rheological behaviour.
As Al-Si-Zn ternary alloys may exhibit the rheological behaviour required for semisolid forming and the excellent final mechanical properties of Al-Zn alloys, we investigated the thermodynamics of the solid-liquid transition of Al-5wt%Si-5wt%Zn alloy (referred to here as Al5Si5Zn), the morphological stability of this alloy in the semisolid range and the corresponding rheological behaviour [5].
Grain size and globule size (a) and roundness shape factor (b) as a function of heat-treatment holding time.
However, long holding times adversely affect process control and the commercial viability of SSM processing.
The authors hope to further investigate the potential of Al5Si5Zn by measuring its mechanical properties and fatigue resistance after appropriate heat treatment.

It helps to provide a scientific framework to understand the design and processing of materials on the micro-scale to achieve the macroscopic properties.
Prediction of Limit Strains in Sheet Metal Forming Due to the small deformation zone, material anisotropy as manifested by the effect of grain orientation affect the flow stress, ductility and the forming limit of the microparts.
The factor f is related to the type of orientations present in region A and region B.
Crystallographic factors such as crystal orientation and dislocation slip have to be taken into account Most of the studies on shear angle theories are associated with work on conventional cutting.

Mach peening process is one of many of techniques utilized for improving fatigue properties.
The compressive residual stress, induced by mach peening, seems to be an important factor for increasing the fatigue strength. 1.

At that time, the transformed energy is affected by the velocity and hardness of the shot ball and the impact angle between the shot ball and the surface.

Therefore, different activation energies and pre-exponential factors are obtained in the two different temperature ranges.

Recently the issue is again being raised for the newly developed pretreatment technology using nanofiltration (NF) membrane which has special separation properties owing to the charge characteristics of its surface separation layer.
Conventionally, physically pretreatments such as mechanical filtration and sand filtration are used.
However, for SWRO, scaling is the most urgent factor which is caused by the divalent ions (Ca2+, Mg2+, and SO42-) in seawater, and UF is not effective for the separation of divalent ions.
Therefore, it can be deduced that not only charge exclusion but also steric hindrance effect have affect the rejection of the divalent ions considerably.
For SWRO desalination, scaling is one of the most important influencing factors, the feed of SWRO should have lower concentration of both sulfate and Ca2+ ions, and the NF membrane should have higher rejection of sulfate ions and Ca2+ions.
