Adding ethane and H2 to the fuel increases the in-cylinder pressure and NOx emission, while fuel dilution with N2 has a critical amount. Based on the correlations of AE signatures and fatigue mechanism, it was found that the AE activities generated during fatigue mechanism were divided into three different stages. The critical impact velocity is defined at 212 m/s. Among them, the minimum cross-sectional area of the R5 central hole specimen is 20% smaller than that of the tensile sample, and the peak load is 28% larger. Thus, to reach the MBT condition, the spark time of ethane is the most retarded one and for methane it is the most advanced. % SiCp composites has been produced by using stir casting technique. In a carburetor system, the air intake pressure is influenced by the degree of opening throttle plate and the Venturi effect which draws the fuel to the combustion chamber. This parameter is emphasized for determining the geometry of the irregularity in crack surface and crack volume. Results indicate that the latent efficiency decreased and in contrast the recovered energy increased with increasing airflow rates. At the same time, stress triaxiality of different specimens was obtained using the method of finite element simulation. In conclusion, these computational techniques are very useful in the study of both degenerative valve disease and failure of prostheses and will be further developed to investigate heart valve failure and subsequent surgical repair. does not retain In this research, geopolymer materials were analyzed and profiled using a statistical approach called 2-level fractional factorial design (2-FrFD).

The objective of the present work is to investigate the effect of Ni content on the damping behaviour of zinc modified alloy using a dynamic mechanical analyser. The measured exhaust emission compositions are used to determine the mode of combustion. With reference to the numerical and experimental study, the results shows a good agreement. Additionally, the simulation predicted mitral valve leaflet displacement during closure, which agreed with the results of our previous data analysis and the results for blood flow velocity during systole condition through the mitral valve outlet, as reported in the medical literature. Eliminating the air filter reduces the air flow restriction in the air intake system resulting in better combustion and less unburned components due to higher air availability. %) ratios to SS 316L/HA were prepared. The samples were directionally solidified in Bridgman vertical apparatus and the temperature is recorded during the cooling. As a result, there is an increase in heat flow that amplifies thrust stability and specific impulses. From the experimental results the optimal configuration of governing variables obtained is pulse-on period 110 µs, pulse-off interval 55 µs, discharge voltage 40 volts, discharge current 170 Amp., wire feed speed 3 m/min and cable tension 8 gram.

In this work a hybrid composite laminates of glass fabric reinforced epoxy with 2%, 4% and 6% graphite were studied. Recommendations and suggestions for improving the energy absorption capacity of RFVs have been made. The experimental data obtained, such as the yield strength, ultimate strength and S-N curve were used as the input parameters in ANSYS Workbench 16.1. The results show that the standard air intake system resulted in rich combustion which then led to incomplete combustion, which was caused by less availability of air for the combustion process. The air gap height value of 10mm exhibits thermal enhancement factor values lesser than 1.0 and hence is not recommended for use as heat transfer enhancement device for the entire Reynolds number range used in the analysis. The flat sheet membranes were prepared via a phase inversion method in which the casting dope solution consists of polysulfone and polyethersulfone separately as polymer, while N-methyl-2-pyrrolidone is used as the solvent material. And then the fracture strain of each specimen was outputted by DIC. a CC BY-NC Editors. The CO2 concentration leaving the reactor was measured by an IR CO2 analyzer.
