Abstract

In the present investigation, microstructure study and tensile behavior of nano ZrO2 particulate reinforced copper alloy composites has been reported. Copper matrix composite containing nano ZrO2 were fabricated by conventional stir casting method.The composites containing 4 wt. % of nano ZrO2 particulates were fabricated for the study. The microstructure of the composite was examined by scanning electron microscopy, images were taken to identify the presence of nano ZrO2 particle in aluminum matrix. Further, tensile behavior of as cast copper alloy and copper alloy-4 wt. % nano ZrO2 composites were studied. Tensile properties like ultimate tensile strength, yield strength and percentage elongation were evaluated as per ASTM standards. Microstructural observation revealed the uniform distribution of particles in the copper alloy matrix. From the analysis, it was found that the ultimate tensile strength and yield strength of composite was increased due to nano ZrO2 particles in the composite. Further, from the study percentage elongation of the composite decreases with the addition of nano ZrO2.

International Journal of Computational Engineering Research, Volume 08 ~ Issue 07 (July – 2018)

Abstract

Photosynthesis has long been looked at as the gold standard for turning sunlight into energy and it only makes sense to look to plants for inspiration when building a new clean technology. Harvard and many other labs have been working on artificial leaves for years. Usually the result is a solar technology that when submerged in water or connected to a water source can split the water molecules into oxygen and hydrogen for use in a fuel cell. Last year, Harvard debuted their bionic leaf which goes beyond that and turns sunlight into liquid fuel. The system uses solar energy to split the water molecules, but also contains a hydrogen-eating bacterium that produces liquid fuel The new system converts sunlight into biomass at an efficiency of 10 percent, which is 10 times better than the one percent achieved by the fastest growing plants. The bionic leaf 2.0, they're using doesn't produce the reactive oxygen, making the system far more efficient and the new system can now produce many more fuels like Isobutanol, Isopentanol and PHB, a bio-plastic precursor.

India
International Journal of Computational Engineering Research, Volume 08 ~ Issue 07 (July – 2018)

Abstract

Urban intersections are a primary concern for traffic engineers; they are the location of many accidents and the cause of most urban delay. There is fixed time slot for each intersection, so there is unnecessary waiting time for the vehicles even though there is less traffic density or no vehicles on other intersections. The aim of this paper is to minimize the waiting time at traffic signals (4-leg intersection and Pedestrian Crossing) resulting in time loss and wastage of fuel, thus it is significant to control the traffic signals in an effective manner. This paper concentrates on Model/Solution for traffic management at T intersection (Three and multiple legged intersections).

International Journal of Computational Engineering Research, Volume 08 ~ Issue 07 (July – 2018)

Abstract

Engineered materials are in demand today owing to their superior mechanical properties with Al-Al2O3 combination being one of the most popular pair in which Al is the matrix and Al2O3 being the reinforcing agent. Present work revolves around the fabrication and characterization of Al/Al2O3 composites with a varying range of Al2O3 starting with 0% and goes up to 40% in steps of 10% each. These composites were fabricated using a uniaxial hot press under 10-5 mbar vacuum pressure and a sintering temperature of 400 °C, 3 ton load under a two hour experimental condition. It was observed during characterization that the relative density of the advanced composite increased with the rise in sintering temperature and the density range changed quasi continuously from 2.665x103 Kg/m3 to 2.709 x103 Kg/m3. At the same time the micro hardness obtained at the top layer (100% Al) was 35.2 HV which gradually increased to 75HV at the layer comprising of 40% Al2O3 as reinforcement. This Advanced Composite can be a good substitute for light weight –high strength material with better wear resisting characteristics at elevated temperatures. These advanced composite are also popularly called as Functionally Graded Composite or simply functionally graded materials.

International Journal of Computational Engineering Research, Volume 08 ~ Issue 07 (July – 2018)

Abstract

This paper studies the peristaltic flow of nanofluids through a two-dimensional channel. The analysis is conducted based on the long wavelength and low Reynolds number approximations. The walls of the channel surface propagate sinusoidally along the channel. The Buongiornio formulation for nanofluidsis employed. Approximate analytical solutions for nanoparticle fraction field, temperature field, axial velocity, volume flow rate, pressure gradient and stream function are obtained. The impact of the pertinent physical parameters i.e. thermal Grashof number, basic-density Grashof number, Brownian motion parameter and thermophoresis parameter on nanoparticle fraction profile, temperature profile, velocity profile and trapping phenomenon are computed numerically. The results of this study demonstrate good correlation with the Newtonian results of Shapiro et al. (1969) [4], which is a special case (GrT = 0, GrF = 0)of the generalized model developed in this article. Applications of the study include peristaltic micro-pumps and novel drug delivery systems in pharmacological engineering..
