Exposure to ambient and household fine-particulate matter is identified as a substantial contributor premature mortality in India, according the Global Burden of Disease Studies. This study examines impacts typical Indian cooking practices on indoor air quality characteristics by monitoring evolution fine ultrafine particle (UFP) concentration dining facility residential educational institute India. The area was spread across kitchen (zone1) hall (zone2). A combination validated low-cost PM...
The severe impacts of emissions from combustion necessitate the need for advanced mitigation techniques. This study focuses on experimentally investigating change in particulate matter (PM) during flame diesel blended with varying quantities titania (TiO2) nano-additives. initial observations using a Scanning Mobility Particle Sizer showed reduction total number concentration (TNC) PM TiO2-nanofuel samples compared to diesel. However, detailed investigations revealed enhancement TNC...
ABSTRACT Magnesium/Teflon/Viton (MTV) pyrotechnic compositions are widely used in various applications. Magnesium is known to oxidize under elevated humidity and temperature conditions. Consequently, the performance of MTV pyrotechnics degrades as they age. Accurate characterization aging process necessary for prediction storage life pyrotechnics. This study investigates hygrothermal an mixture using accelerated aging, thermogravimetry (TG), differential scanning calorimetry (DSC), thermal...
An experimental investigation was conducted to characterize the monopropellant droplet combustion of pure and blended isopropyl nitrate (IPN), suspended on quartz fibers in a quiescent atmosphere. The blends were prepared by mixing IPN with less viscous n-heptane percentages 10 90% weight IPN, highly dibutyl sebacate (DBS), IPN. Ignition achieved using heated 60 μm nichrome wire. While dependence initial diameter investigated size range 1 2 mm, studies carried out diameters mm for...
An experimental investigation was conducted to characterize the strand combustion of pure isopropyl nitrate (IPN) blended with a known de-sensitizer dibutyl sebacate (DBS). The blend prepared 75% IPN mixed 25% DBS by weight so as mimic composition Otto fuel II. Quartz tubes 3, 5, 7.5, and 9 mm in diameters were utilized create strands various diameters. experiments quiescent atmosphere air ambient pressure varied from 5 40 bar steps bar. Ignition achieved using heated 60 μm Nichrome wire...
Air pollution is one of the leading causes premature death across world. To gain valuable insights into ambient fine particulate matter (PM) concentrations, a combination regulatory monitoring networks, satellite retrievals air-quality-related substances, and air quality models are typically employed. Studies reveal persistent exceedance World Health Organization national standards, particularly in developing nations. It crucial to recognize that numerous regions Asia Africa still need...
