In this paper designing of three cylinder pneumatic engine is done on Solidworks and also static analysis is done on it. The design used for pneumatic cylinders is highly efficient and can be used for vehicle propulsion and lifting light weights. The main advantage of air radial engine is that no pollution is produced…
2 , SADEGHI, H. 2 , and KHAEF, N. 2 ABSTRACT - Calotropis procera, Apocynaceae, is a wild perennial shrub that originated in the Persian deserts. It is known to provide key resources in degraded ecosystems to about 80 animal species. C. procera is regenerated by seed and produces lots of small seeds that are dispersed…
This paper investigates the modeling of surface tension, surfactant and suction of micro droplets. A parallel volume of fluid code has been developed to simulate interfacial flows with surface tension and surfactant. The continuity, momentum and energy equations were used to formulate the governing equations for the p…
The ultrasonic velocity, density and viscosity have been measured for the binary mixtures of 2'chloro-4met hoxy-3nitro benzilic acid (2C4MBA) with polar and non-polar solvents at 298K. The experimental data have been used to calculate the Density (ρ) and acoustical parameters namely, ultrasonic velocity (U), adiabatic…
Tato bakalařska prace se zabýva popisem a kvantifikaci postupu připravy koloidnich roztoků střibrných nanocastic s předem definovanými tvary a velikostmi (tedy s předem definovaným absorpcnim maximem ve viditelnem spektru) a jejich naslednou cilenou agregaci vedouci k požadovane maximalni plazmonove rezonanci s dopada…
Nanocrystalline cobalt substituted nickel zinc ferrite have been synthesized by coprecipitation technique using oxalate precursors. The variation of coercive force Hc with the cobalt content is minimum at x=0.01 and it is in creases for x ≥0.03. The wall energy (Ew) and magnetic crystalline anisotropy K 1 increases wi…
Calcium carbonate scale is one of the challenges which must to be solved during the process of mass production in middle to high temperature geothermal fields. The formation trend of the calcium carbonate scale in the Langjiu Geothermal Field of Tibet is apparent. The speed of the scaling is 2 mm/d. In this paper, bas…
A second order two scale computational homogenization approach for modeling deformation responses of heterogeneous material at large strain is proposed.The structure at macrolevel is discretized by the C 1 continuity displacement based triangular finite elements derived in this contribution, while the standard C 0 qua…
The stress state (SS) of various alternate schemes of reinforcing central inlets in elliptical bottoms is examined in [1, 2] by methods of the theory of shells. Stress risers that develop with the use of superposed plates were not considered in these studies. In this study, it is demonstrated that this must be account…
Methods of the approximate estimations of fatigue durability of composite airframe component typical elements which can be recommended for application at the stage of outline designing of the airplane are generated and presented.
The short-range order (SRO) in Pd78Cu6Si16 liquid was studied by high energy x-ray diffraction and ab initio molecular dynamics (MD) simulations. The calculated pair correlation functions at different temperatures agree well with the experimental results. The partial pair correlation functions from ab intio MD simulat…
O presente trabalho estudou o efeito da energia de soldagem e do tratamento térmico de bake hardening sobre as propriedades mecânicas e metalúrgicas de juntas de aço Dual Phase 1000, soldadas a topo, pelo processo MAG. Primeiramente os espécimes foram soldados utilizando diferentes energias de soldagem. Foram então se…
Nella parte sperimentale sono stati easminati diversi campioni di acciai sottoposti a varie temperature di ricottura e differenti tempi di perm anenza. Le temperature del tratamento termico sono state selenzionate entro l'intervallo 300 -1000oC, mentre i tempi di permanenza sono variati da 60 a 240 minuti. Dopo la ric…
Trichloroethylene (TCE) is known as one of the persistent pollutants of soil and groundwater. TCE has carcinogenicity and should urgently be decontaminated. In this research, Fenton reaction and ultrasonic (US) irradiation were used for TCE decomposition as low cost and widely targetable advanced oxidation processes.…
The effect of stitching parameters on the puncture resistance properties of high strength fabric system was investigated. There are three objectives in this study; to investigate the effect of stitching patterns on the puncture resistance properties of the high strength fabric system, to investigate the effect of stit…
Atmospheric pressure plasma-enhanced chemical vapor deposition (AP-PECVD) of biomedical coatings is carried out in a dielectric barrier discharge (DBD) reactor. Argon is used as the inert carrier gas, entraining volatile organic precursors into the discharge zone. Precise measurements of the energy dissipated per disc…
Abstract: The oysters ( Crassostrea cattuckensis ) were exposed to sub lethal levels of mercury for 15 days for metal accumulation and 15 days of metal detoxification. The oysters, which served as experimental control after 15 days the protein (mg/100 mg) content showed more in adductor muscle (32.63) followed by siph…
In this work, a numerical analysis is carried out to study the behaviour of a woven fabric composite plate under low velocity impact. The finite element simulation is carried out to investigate the stress distribution during the impact on woven fabric laminated composite plate. The usefulness of the developed numerica…
Cadmium Tartrate Oxalate single crystals doped with barium were grown by controlled diffusion in silica gel at ambient temperature. The maximum uptake of barium in Cadmium Tartrate oxalate single was determined. Effect of barium dopant on the growth and morphology of Cadmium Tartrate oxalate single crystal was studied…
In recent years, countries around the world are trying to use high efficiency plants to produce energy with low fuel consumption and consequently low operation costs. The molten carbonate fuel cell (MCFC) power plant is an emerging high efficiency, ultra-clean power generator utilizing a variety of gaseous, liquid and…
