Cup drawing is one of the important operations in sheet metal forming. Manufacturing of the aluminium base cup involves several stages such as blanking, first drawing, second drawing, taper formation and trimming. This increases the process time. An attempt has therefore, been made to develop a comprehensive, rigorous, yet easily-workable method of analysis for designing a die set to combine the intermediate stages of drawing process. Conventional drawing, inverted drawing and warm forming processes are experimented for yielding successful drawing in single setup. Die sets are separately designed for above said processes.

Phase Change materials (PCMs) absorb and release latent heat during their phase transition nearly at constant temperature. The latent heat storage phenomena using PCMs provides much higher storage density, with a smaller or zero temperature difference while storing and releasing of heat. PCMs have 5-14 times more heat capacity per unit volume than sensible storage materials that merits their usage as passive thermal control systems. They are effectively complemented with active thermal control systems in order to minimize their duty cycles and optimize the capacity.

Vibration suppression has always been an important issue in developing efficient motion control systems. Traditionally, in a mechanical system, the vibrations are suppressed by adding more material to the system in order to increase the rigidity. However, recent advancements in mechatronics, has provided with many alternative solution that avoids excess material addition and increased performance. This paper attempts to summarize various methods that are being developed for vibration detection and suppression. The techniques included in this paper are motion control strategies based on sensors, sensor-actuator and sensorless controllers.

International Journal of Mechanical and Industrial Engineering
The thermal conductivity of heating or cooling fluids is a very important property in the development of energy efficient heat transfer systems, which is one of the important needs of many industries. However, low thermal conductivity is a primary limitation in developing energy-efficient heat transfer fluids that are required for cooling purposes. Nanofluids are nanotechnology-based heat transfer fluids that are engineered by stably dispersing nanometer-sized (below 100nm) solid particles (such as ceramics, metals, alloys, semiconductors, nanotubes, and composite particles) in conventional heat transfer fluids (such as water, oil, diesel, ethylene glycol and mixtures) at relatively low particle volume concentrations. These ...

Nucleate Pool Boiling Heat Transfer In Ulticomponent Mixtures On Surfaces: An Review, Sudev Das, Swapan Bhaumik
International Journal of Mechanical and Industrial Engineering
Boiling of multicomponent mixtures is characterized by a close linking between heat and mass transfer processes, with the evaporation rate usually being limited by the mass transfer process. This is significantly different from single and binary component systems where interfacial mass transfer rates are normally very high. Information on pool boiling of binary mixtures is widely available in the literature, whereas research on forced convective boiling of mixtures has become significant only over the last few years. This paper presents a brief review of experimental results obtained in pool boiling of ternary mixtures and also the empirical or theoretical correlations ...
