Minimum quantity lubrication (MQL) is a cost-effective and environmentally friendly alternative to flood cooling. MQL spray jet has been shown to have potential to be applied successfully in different machining processes. Since the amount of lubricating liquid employed in MQL jet is very low, it is necessary to generate and apply the MQL spray efficiently. However, efficient application of MQL is not only related to spray atomization characteristics and delivery parameters but is also affected by machining conditions. The present paper demonstrates a theoretical and experimental investigation on the spray atomization and delivery parameters in the grinding process of Al2O3 engineering ceramics. The spray atomization characteristics studied are carrier gas velocity, liquid droplet size and liquid droplet velocity. Experiments were performed to verify the delivery parameters of MQL spray including nozzle angle, nozzle distance, lubricant flow rate and gas flow rate in the case of Al2O3 ceramics grinding. The experimental results confirm the theoretical outcomes and indicate that by applying optimal spray delivery parameters efficient lubrication takes place. Moreover, efficient lubrication of Al2O3 ceramics grinding can decrease the challenges existing in ceramics grinding processes by reducing grinding forces and surface roughness. 相似文献

Porous media grain size distribution and hydrodynamic forces effects on transport and deposition of suspended particles 总被引:1,自引:0,他引:1

The effects of porous media grain size distribution on the transport and deposition of polydisperse suspended particles under different flow velocities were investigated. Selected Kaolinite particles(2–30 μm) and Fluorescein(dissolved tracer) were injected in the porous media by step input injection technique. Three sands filled columns were used: Fine sand,Coarse sand, and a third sand(Mixture) obtained by mixing the two last sands in equal weight proportion. The porous media performance on the particle removal was evaluated by analysing particles breakthrough curves, hydro-dispersive parameters determined using the analytical solution of convection–dispersion equation with a first order deposition kinetics, particles deposition profiles, and particle-size distribution of the recovered and the deposited particles. The deposition kinetics and the longitudinal hydrodynamic dispersion coefficients are controlled by the porous media grain size distribution. Mixture sand is more dispersive than Fine and Coarse sands. More the uniformity coefficient of the porous medium is large, higher is the filtration efficiency. At low velocities, porous media capture all sizes of suspended particles injected with larger ones mainly captured at the entrance.A high flow velocity carries the particles deeper into the porous media, producing more gradual changes in the deposition profile. The median diameter of the deposited particles at different depth increases with flow velocity. The large grain size distribution leads to build narrow pores enhancing the deposition of the particles by straining. 相似文献

Human bocavirus (HBoV) is predominantly found in the respiratory tract infections and in the stool of patients with gastroenteritis symptoms. However, data on the prevalence of HBoV genotypes in environmental samples are limited. Here we addressed the prevalence of HBoV in sewage collected from three different wastewater treatment plants in Egypt. HBoV-1, HBoV-2, and HBoV-3 were detected, whereas none of the samples were positive for HBoV-4. The median concentration of HBoV in influent samples was 8.5 × 103 GC/l for HBoV-1, 3.0 × 104 GC/l for HBoV-2, and 2.5 × 104 GC/l for HBoV-3. The concentration was reduced but not completely removed in the effluent samples. The median concentration in the outlet samples was 2.9 × 103 GC/l for HBoV-1, 4.1 × 103 GC/l for HBoV-2, and 2.1 × 103 GC/l for HBoV-3. Moreover, no seasonality pattern of HBoVs was found. The high incidence of HBoV in sewage samples provided an evidence of its circulation in the local population. Although the role of HBoV in respiratory or gastro-intestinal infections still remains to be fully elucidated, the risk of infection via contaminated water should be taken into consideration. 相似文献
