Abstract - In the present industrial sectors like aircraft,
figures a major downside of the incessant innovation. Hence, there arises a pressing need for enhancing the cooling methodology to afford the processor base temperature in a convenient threshold range. It has been reported that conventional air-cooling techniques remain insufficient to meet such challenges [1]. In recent days, investigation into the concept of heat removal by liquids has attracted heightened interest among researchers in the area of materials science. Liquids function in heat removal process better than air due to their specific thermal characteristics. Research on this subject can be categorized in terms of the methods adopted. One of the methods is modification of the heat sink geometry in order to enhance surface area used with conventional fluid. Another method used is by altering the thermo physical properties of fluids used with plain geometry for maintaining proper functioning of electronic devices [2].
marine, bio-medical, chemical, etc., the usage of titanium has gained lot of interest due to its improved properties like strength, corrosion resistance, etc. Because of the improved properties like, higher hardness, toughness and poor thermal diffusivity make the material to fall under the category of hard-to-machine and this gave rise to the development and utilization of non - traditional machining processes. Machining of such components at a micro level have gained lot of attraction in the present industrial sector. There are many such machining processes used for machining micro and mini components. The accuracy and precision of components machined through such conventional processes are the challenging one. This gave rise to one of the non-traditional machining process called Wire electrical discharge turning (WEDT) process, which machines any electrically conductive cylindrical components of any shape and dimension. As a present research work, the process ability of WEDT process during machining of Ti-6Al-4V alloy using uncoated and diffusion annealed zinc coated brass wire is conducted. To conduct the experiments, a low cost rotary spindle setup is fabricated in-house. In order to predict the crater formation on the work material for the given input machining conditions, the numerical modelling is conducted using COMSOL Multiphysics 5.2 platform. A set of pilot experiments are conducted to validate the simulated results and found results are in agreement with each other, thus assuming the model to be correct to proceed further with the main experimentation. The samples machined with uncoated and diffusion annealed zinc coated brass wires are subjected to various mechanical and metallurgical studies to analyze the effect of WEDT process. Keywords: Turning, Zinc-coated, corrosion, Characterization.
Optimization,
Recently, in an examination on the micro channel heat sinks, it was reported that by reducing the channel’s hydraulic diameter, enhanced heat transfer possibility is attained. Further, a fluid carrying nanoparticles in basefluid has shown encouraging betterment for enhanced heat transfer applications. These fluids are known as “Nanofluids”, which are a relatively advanced class of fluids that consist of a base fluid with nano-sized particles (1– 100 nm) suspended within them. These suspended particles are metal or metal oxide, which enhance conduction and convection coefficients, permitting enhanced heat transfer. Some distinctive nanofluids are ethylene glycol-based copper nanofluids and water-based copper oxide nanofluids [3]. Also, the fabrication of micro channel heat sinks for the transfer of heat flux requires considerable expertise. The smaller the electronic components are, the more complex its thermal management becomes. In such cases, surface roughness plays an principal role in pool and flow boiling in micro channels. It is also noted that an increase in surface roughness brings about pressure dip and velocity variations in a single-phase flow. Hence, optimization of surface roughness coupled with other characteristics becomes significant. Not just the cooling techniques, and surface area as well as its roughness, but
