Abstract

A parametric study of the skin friction coefficient and drag force of Titania/water nanofluid flow over an isothermal flat plate at stationary condition is conducted. With the help of similarity analysis, the governing equations of continuity and momentum are reduced into nonlinear differential equations which are subsequently solved numerically using a shooting method in Engineering Equation Solver (EES) software. The effect of volume fraction on the different flow parameters is evaluated. The numerical results show that density and dynamic viscosity increase with increase in particle volume fraction of nanoparticles. The thickness of hydrodynamic boundary layer reduced with an increase in nanoparticle volume fraction in base fluid. Skin friction coefficient and wall shear stress increase in magnitude with the inclusion of nanoparticles in base fluid but decrease along the direction of flow. The results are displayed graphically and they contribute to understanding the interesting aspects of nanofluids.

Abstract

In the present work, Ni based powder was deposited on stainless steel substrate using a low velocity flame spray technique. The coating of thickness 300 μm was developed using a neutral oxy-acetylene flame. To enhance the microstructure and wear resistance, the coated specimens were heat treated and cooled using various cooling strategies, such as, air, water, and furnace cooling. The microstructure of the as-sprayed and heat treated specimens were studied using SEM. Some unmelted particles and pores were also present in the as-sprayed specimen. The watercooled specimen exhibits equiaxed structure, while the furnace cooled coating demonstrates a coarse structure. The microhardness of the specimens was evaluated using a Vicker's microhardness tester. The water-cooled specimen exhibits highest hardness and wear resistance.

Abstract

In the present work, the ferrous components used in gear, and cam shaft were made by using Powder Metallurgy (PM) technique. Powder Metallurgy is a widely used technique for making harder materials which are difficult to make by other conventional processes. The five components were made by mixing iron, copper and carbon in different proportions by taking carbon composition constant. The fabricated components were characterized through microstructural investigation and microhardness tester. The microstructural study reveals the fabricated components were dense with no porosity. Microhardness test reveals that the sample number five has a maximum hardness as compared with other components produced through PM technique.

Abstract

To improve pattern making from Fused Deposition Modelling (FDM) machine for reduction of scrap and environmental hazard, parameters of FDM machine is optimized for compression strength and surface roughness together in this study. Taghuchi's method and utility concept is applied to find sets of parameter that can globally optimize the compression strength and surface roughness, as these are the most important selection characteristics for a pattern. From the result, it is found out that layer thickness is the most influencing parameter in pattern making, which significantly control both characteristic responses. This study also shows that it is possible to optimize compression strength and roughness with this method, and gives edge to FDM machine to other methods of pattern making.

Abstract

This paper deals with the study of different types of heat exchangers used in engineering industries such as plate type, shell and tube, radiator and cooling towers. The effect of different performance and geometrical parameters to obtain optimal heat transfer rate is studied. The main parameters are temperature of inlet and outlet working fluids, mass flow rates, pressure drops, fin design, coolants used and flow consideration. The optimal design of the geometry can be obtained easily and effectively by using CFD tools to experiment a compact and efficient model.
