1Meshless Method for Analysis of Permeable Breakwaters in the Proximity of A Vertical Wall显示文摘In the present work, the improved version of the meshless singular boundary method(ISBM) is developed for analyzing the performance of bottom standing submerged permeable breakwaters in regular normally incident waves and in the proximity of a vertical wall. Both single and dual prismatic breakwaters of rectangular and trapezoidal forms are examined. The physical problem is cast in terms of the Laplace equation governing an irrotational flow and incompressible fluid motion with appropriate mixed type boundary conditions, and solved numerically using the ISBM. To model the permeability of the breakwaters fully absorbing boundary conditions are assumed. Numerical results are presented in terms of hydrodynamic quantities of the reflection coefficients. These are firstly validated against the results of a multi-domain boundary element method(BEM) developed independently for a previous study. The agreement between the results of the two methods is excellent. The coefficients of reflection are then computed and discussed for a variety of structural conditions including the breakwaters height, width, spacing, and absorbing permeability. Effects of the proximity of the vertical plane wall are also investigated. The breakwater's width is found to have only marginal effects compared with its height. Permeability tends to decrease the minimum reflections. These coefficients show periodic variations with the spacing relative to the wavelength. Trapezoidal breakwaters are found to be more cost-effective than the rectangular breakwaters. Dual breakwater systems are confirmed to perform much better than single structures.Nadji CHIOUKH Karim OUAZZANE Yal??n YüKSEL Benameur HAMOUDI Esin ?EVIK 2019China Ocean Engineering2019,33,2:6

3Effect of Porosity on the Mechanical Properties and Wear Performance of 2% Copper Reinforced Sintered Steel Used in Shock Absorber Piston Production显示文摘Powder metallurgy(P/M)method has mainly been used to produce automobile parts such as self-lubrication beds,shock absorber parts,and gear wheels.In order to investigate the effect of porosity on the mechanical and tribological properties in sintered steel,specimens with 10%,15%,and 20%porosity were produced in a 10 mm×10 mm×55 mm prismatic shape by pre-alloying powders of the MPIF Fe-C-0.205 alloy used in the production of shock absorber pistons.Sintering was carried out at 900-C for 45 min in an argon atmosphere. Tensile,charpy,and microhardness tests were performed on these specimens.In addition,the wear performance of a 2%Cu reinforced sintered steel alloy under dry sliding conditions was determined.Metallographic studies such as pore formation,worn surface,and fractured surface analyses were performed by scanning electron microscopy and optical microscopy.The results indicate that irregular pore formation tendencies increase with an increase in porosity(%).Furthermore,an increase in porosity was shown to decrease the mechanical properties and increase the wear trace area and the friction coe-cient of sintered steel.Bekir Yalin 2009Journal of Materials Science & Technology2009,25,5:2

5Effect of sodium replacement on the quality characteristics of pastırma(a dry-cured meat product)显示文摘This study aims to investigate the effect of sodium replacement on the quality characteristics of pastırma.For this purpose,pastırma production with four different salt mixtures(Ⅰ.100%NaCl;Ⅱ.50%NaCl+50%KCl;Ⅲ.40%NaCl+40%KCl+20%CaCl_(2);Ⅳ.30%NaCl+40%KCl+20%CaCl_(2)+10%MgCl_(2))were carried out using traditional method.The use of different salt mixtures for pastırma had no statistically significant effect on the microbial counts and residual nitrite of the final product.The a*and b*values were affected by this treatment.The salt mixture containing CaCl_(2) or CaCl_(2)+MgCl_(2) significantly decreased the pH values and sensory scores.The eighteen volatile compounds were affected by the salt mixtures.Na^(+),K^(+),Ca^(2+),and Mg^(2+)had a certain increase depending on their ratio in the salt mixtures.The highest Cathepsin activity in all pastırma samples was observed in Cathepsin B+L.The salt mixture with NaCl+KCl+CaCl_(2)+MgCl_(2) increased acid lipase activity.However,this mixture had no significant effect on neutral lipase activity.BarışYalınkılıç Güzin Kaban Mükerrem Kaya 2023Food Science and Human Wellness2023,12,1:2
