BACKGROUND Potentially infected individuals ('source') are sometimes encouraged to use face masks to reduce exposure of their infectious aerosols to others ('receiver'). To improve compliance with Respiratory Source Control via face mask and therefore reduce receiver exposure, a mask should be comfortable and effective. We tested a novel face mask designed to improve breathability and filtratio...
The flowfield characteristics are experimentally studied in the inter-nozzle region of free jets from twin and triple supersonic nozzles. nozzle is designed for Mach number 2.0, spacing twice exit diameter. impact multiple on flow such as jet spread, core, shock wave structure explored using pitot pressure readings schlieren technique. For 2.0 at ratio (NPR) 2 8.5, pressures measured along cent...
In recent decades, solid fuel combustion propulsion of spacecraft has become one the most popular choices for rocket systems. The reasons this success are a wide range applications, lower production costs, simplicity, and safety. rocket’s plumes leave nozzle at high temperatures; hence, knowledge produced infrared (IR) emissions is crucial aspect during design tests motors. Furthermore, plume c...
Polyoxymethylene dimethyl ether (PODE) is a low-viscosity oxygenated fuel that can improve the volatility of blended fuels. In this work, macroscopic and microscopic spray characteristics diesel-PODE3-4 under different ambient temperatures injection pressures (IP) are studied. The studied blends consisted pure diesel (P0), two blend fuels 20% (P20) 50% (P50) by volume fraction PODE3-4. Mie scat...
One of the most essential inherent characteristics a combustible mixture is laminar burning velocity. Because its relevance, many methods for measuring flame velocity have been devised. advanced procedure was used to derive in constant volume vessel blends iso-octane and n-heptane/air mixtures this study: particle imaging velocimetry. Based on precise flow field with vectors, velocimetry (PIV) ...
Crystallization coupled with gravity removal of depleted interstitial melt has long been recognized as a mechanism of magma differentiation. Similarly, heat released by synplutonic basaltic magma intrusions has long been recognized as capable of driving convection in granite chambers. Direct evidence of these processes has seldom been described in granites. In the Tavares pluton, we mapped a nu...
