Asian Journal of Engineering and Applied Technology https://ojs.trp.org.in/index.php/ajeat <p>Asian Journal of Engineering and Applied Technology (AJEAT) is a half-yearly international journal devoted to the publication of peer-reviewed original high-quality research papers and review papers in all disciplines of engineering and applied technology.</p> The Research Publication en-US Asian Journal of Engineering and Applied Technology 2249-068X Aerodynamic Analysis of Micro Aerial Vehicle Rotor Blade at Low Reynolds Number https://ojs.trp.org.in/index.php/ajeat/article/view/2953 <p>The numerical simulation of micro aerial vehicle (MAV) rotor blade aerodynamics is highly challenging in the field of rotor aerodynamics. The aim of this paper is to present a computational fluid dynamics (CFD) study on the aerodynamics analysis of micro aerial vehicle rotor blade at low-Reynolds number by means of Spalart-Allmaras turbulence model. The KA152313 airfoil, which is dedicated to mid to small-scale rotorcraft, e.g. MAV is chosen to design the rotor blade. The rotor blade was investigated in three different pitch configurations, which are GP13º, GP12º and GP11º and the aerodynamics characteristics are analyzed respectively. The CFD results of the analysis is used to compare the aerodynamic characteristics, e.g. pressure force, shear force and pitching moment on the chord surface of the rotor blades at different pitch configurations.</p> Md.

The inorganic salts used were NaCl, KI, and MgCl2·6H2O. The influence of factors such as amount of salt, phase volume ratio, initial aniline concentration in feed-water solution, and temperature on the distribution of aniline was investigated. It was found that addition of 5% NaCl shows an appreciable salting-out effect on distribution of aniline. It was also found that the distribution of aniline was favoured at low aniline concentrations, and a phase volume ratio of toluene to water of little above 1.0. It is also found that the dissociation of salt added plays an important role in aniline extraction and the effect of cation and/or anion as predicted by the Hofmeister series may not be always followed in all cases. The distribution of aniline between water and toluene is found to be endothermic in nature.</p> Shrikant J. Wagh Shaktisingh G.
