(2020-02-24)The flammable and explosive hazards of aerosol, also referred as mist or spray, are usually ignored compared with the flammable and explosive hazards related to gas and dust. Numerous incidents in various industries have ...
-
(2013-07-30)The studies in this dissertation aim at advancing our scientific understandings about physical processes involved in the aerosol-cloud-precipitation interaction and quantitatively assessing the impacts of aerosols ...
-
(2023-03-03)Under humid atmospheric conditions, pollen grains can rupture creating pollen grain fragments referred to as subpollen particles (SPPs). This study evaluated environmental conditions needed to emit SPPs and measure the ...
-
(Texas A&M University, 2006-04-12)Tests were conducted to characterize mixing in a square and a rectangular duct with respect to suitability for single point sampling of contaminants. Several configurations, such as a straight duct with unidirectional flow ...
-
(Texas A&M University, 2006-08-16)A Differential Mobility Analyzer/Tandem Differential Mobility Analyzer (DMA/TDMA) was used to measure size distributions, hygroscopicity, and volatility during the May 2003 Aerosol Intensive Operational Period at the Central ...
-
(2014-08-28)The Captive Aerosol Growth and Evolution (CAGE) Chamber System is an tool designed to study the evolution of aerosols under conditions identical or similar to those of the surrounding environment. Our motivation was to ...
-
(2017-03-14)Throughout the process industries, there have been numerous fire and explosion incidents related to aerosols. Aerosols may form from rapid condensation of vapor or accidental leakage of pressurized liquid. However, their ...
-
(2009-05-15)This research reports the results of experimental and numerical studies performed to characterize aerosol deposition on four different types of commercially available screens (electroformed-wire, woven-wire, welded-wire, ...
-
(2009-05-15)Aerosol particles have profound impacts on human health, atmospheric radiation, and cloud microphysics and these impacts are strongly dependent on particle sizes. However, formation and growth of atmospheric particles are ...
-
(2013-12-02)The existence of flammable aerosols creates fire and explosion hazards in the process industry. Due to the operation condition of high pressure circumstances, heat transfer fluids tend to form aerosols when accidental ...
-
(2017-04-11)Interactions with atmospheric water are central to aerosol impacts on health, climate, and visibility. Many atmospheric aerosol constituents take up water in sub-saturated conditions, enhancing their impact on climate and ...
-
(2009-05-15)Coxiella burnetii is an intracellular pathogen that can cause both acute and chronic disease (Q fever) in humans and infects many animals with varying clinical illness and persistence. A guinea pig aerosol-challenge model ...
-
(2018-06-12)The concentrations of cloud condensation nuclei (CCN) modulate cloud properties, rainfall location and intensity, and climate forcings. This work assesses uncertainties in CCN measurements and the apparent hygroscopicity ...
-
(2009-05-15)In this dissertation, a two-moment bulk microphysical scheme with aerosol effects is developed and implemented into the Weather Research and Forecasting (WRF) model to investigate the aerosol-cloud interaction. Sensitivities ...
-
(Texas A&M University, 2006-08-16)This dissertation describes the use of measured aerosol size distributions and size-resolved hygroscopic growth to examine the physical and chemical properties of several particle classes. The primary objective of this ...
-
(Texas A&M University, 2006-08-16)Soot particles released from fossil fuel combustion and biomass burning have a large impact on the regional/global climate by altering the atmospheric radiative properties and by serving as cloud condensation nuclei (CCN). ...
-
(2014-12-12)An existing flame speed bomb, which uses optical techniques to measure laminar flame speed, was employed to study the fundamental phenomena of flame propagation through a uniformly dispersed aerosol. In a previous thesis ...
-
(Texas A&M University, 2004-09-30)Mist or aerosol explosions present a serious hazard to process industries. Heat transfer fluids are widely used in the chemical process industry, are flammable above their flash points, and can cause aerosol explosions. ...
-
(2023-07-09)Retrievals utilized in ice cloud and mineral dust aerosol remote sensing contain uncertainties from both forward models and measurements. These uncertainties are present in the retrieval products and propagate to atmospheric ...
