Failure Analyses of 16 mm Thick SA 516 GR 70 Auto Clave
Abstract: With the acceleration of global industrialization, there is a demand for high-or low-pressure storage of liquids or gases. Because of the complicated operating conditions that will inevitably encounter a possible hazard, pressure vessel design is a critical responsibility. Previous failure studies have revealed that the presence of local loads and discontinuities increases pressure vessel fracture. As a result, a detailed examination of pressure vessel steel from the standpoint of fracture …

Performance Analysis of Space Shift Keying and Quadrature Space Shift Keying for MIMO Channels
Abstract: In wireless communication the propagation channel is characterized by multipath propagation due to scattering on different obstacles. MIMO takes advantage of multi-path and uses multiple antennas to send multiple parallel signals from transmitter. “Multi-path” occurs when different signals arrive at the receiver at various times. MIMO exploits the space dimension to improve wireless systems capacity, range and reliability. There are two different modulation techniques that exploits the best features of …

Bovine Milk in Andean Peru: Pastures
Abstract: Modern world faces a malnourishment crisis; two billion people with micronutrient deficiency and around 200 million children under five are either stunned or low-weighted. In rural areas such as that of Peruvian territory, the scenario is more prevalent and linked to poverty. Milk as a dietary complement produce is poorly consumed in Peruvian Andes and in Peruvian territory, early estimates indicate that no more than 10 kg/year/person of milk is …

Numerical Study and Comparison of Passive Mixing in Helical Micromixers
Abstract: A passive mixing inside three micromixers has been studied with water as the mixing fluid. Since the mixing at the micro-level is governed by species diffusion hence it is a time-consuming process that requires an extended length of micromixer for the required amount of mixing. The present study tackles this problem by introducing two helical micromixers, a Three-dimensional helical micromixer (TDHM), and TDHM having four inlets (TDHM-FO). These micromixers need …

Effect of Initial Temperature and Diameter of Ethanol Droplet on Evaporation Dynamics in Convective Air Medium
Abstract: Ethanol is a suitable biofuel as it has fewer toxic emissions and higher-octane numbers. For spray combustion applications, the gas phase motion must be considered while numerically investigating the fundamental aspects of droplet evaporation and combustion processes. Hence, we have numerically simulated the evaporation dynamics of an isolated spherically shaped ethanol droplet under a forced convective air environment in the absence of gravity. The momentum transfer between two phases is …
