The filling of cans is performed in a manner similar to the filling of glass bottles. Nevertheless, the evacuation cannot take place because the can axial pressure resistance does not allow the application of a vacuum. Therefore, only purging with CO2 or... 

Figure 13.6 shows the top end of the column surface which is constrained in the x and y-direction. The bottom end of the column is constrained in the x-direction and free in the y-direction due to upward axial pressure (0.125fc). The tip of the beam is constrained in the y-direction for application of displacement which is 50 mm. 

By far, the largest application of the axial compressor is the aircraft jet engine. The second most common usage is the land-based gas turbine, either the aircraft derivative or generic designed type. In last place of the applications comes the process axial compressor. All principles of operation are exactly the same. About the most obvious difference is that the gas turbine compressor is a higher pressure ratio machine and therefore has more stages. 

Vane axial fans develop a greater static pressure than tube axial fans. They are constructed from a variety of materials, depending on the application. They may use either a direct drive or a belt drive. More expensive models... 

The axial fan is being built in larger capacities and for higher pressure characteristics and is finding increasing application. Figure 12-124 shows a vaneaxial unit. A tubeax-... 

The penetrating power of a shaped charge is approximately proportional to the cube of its diameter, but also very dependent on maintenance of exact axial symmetry during construction. It is also proportional to the detonation pressure of the explosive used, so that suitable fillings are cast Pentolite or RDX/TNT. Well-known applications of shaped charges are in the British PIAT and American bazooka. 

Cross-flow filtration systems utilize high liquid axial velocities to generate shear at the liquid-membrane interface. Shear is necessary to maintain acceptable permeate fluxes, especially with concentrated catalyst slurries. The degree of catalyst deposition on the filter membrane or membrane fouling is a function of the shear stress at the surface and particle convection with the permeate flow.16 Membrane surface fouling also depends on many application-specific variables, such as particle size in the retentate, viscosity of the permeate, axial velocity, and the transmembrane pressure. All of these variables can influence the degree of deposition of particles within the filter membrane, and thus decrease the effective pore size of the membrane.
