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 …

Extent of Lingual Coarticulation: A Crosslinguistic Study Using Ultrasound Imaging
Abstract: In the recent past, Ultrasound imaging has been used extensively as a tool to measure coarticulation. The extent of coarticulation is the magnitude of distance between tongues contours of adjacent phonemes that varies based on the articulatory dynamics of each phoneme. This lack of invariance is language-specific which is related to the articulatory constraint properties of a particular language. In this context, the present study aimed to analyse the magnitude …
