A Variable-Density Fictitious Domain Method for Particulate Flows with Broad Range of Particle-Fluid Density Ratios

Creator:: Apte, Sourabh V. and Finn, Justin R.
Abstract:: A numerical scheme for fully resolved simulation of particle–fluid systems with freely moving rigid particles is developed. The approach is based on a fictitious domain method wherein the entire particle–fluid domain is assumed to be an incompressible fluid but with variable density. The flow inside the particle domain is constrained...

Radiative heat transfer in combustion applications : parallel efficiencies of two gas models, turbulent radiation interactions in particulate laden flows, and coarse mesh finite difference acceleration for improved temporal accuracy

Creator:: Cleveland, Mathew A.
Abstract:: We investigate several aspects of the numerical solution of the radiative transfer equation in the context of coal combustion: the parallel efficiency of two commonly used opacity models, the sensitivity of turbulent radiation interaction (TRI) effects to the presence of coal particulate, and an improvement of the order of temporal...

Measuring and modeling solids movement in a large, cold fluidized-bed test facility

Creator:: Daous, Muhammad A.
Abstract:: Solids movement in large-particle fluidized beds was studied in an 18 in x 18 in (46 cm x 46 cm) tube-filled, cold fluidized bed test facility. Direct measurement of local solid mass flux in two dimensions at various locations inside the bed was made possible by a new instrument developed...

Intertidal zone particulate organic carbon redistribution by low-tide rainfall

Creator:: Chen, Si, Torres, Raymond, and Goñi, Miguel A.
Abstract:: We present field data and data from the literature to highlight the effects of low-tide rainfall on particulate organic carbon (POC) redistribution in intertidal landscapes. The POC exchanges reported from disparate but related studies were standardized to a storm-induced exchange rate (gPOC m⁻² mmRain⁻¹) and compared. Results show that these...

Effectiveness of a fluidized bed in filtration of airborne particulate of submicron size

Creator:: Black, Charles Hartgraves
Abstract:: Submicron particulate (mean size of 0.52 microns) was filtered from air at substantially atmospheric temperature and pressure by passing air up through a bed of fluidized glass shot in a two inch column. Removal efficiency, defined as the percentage removal of particulate from the air stream, was essentially constant during...

Particulate organic matter export by two contrasting small mountainous rivers from the Pacific Northwest, U.S.A.

Creator:: Goñi, Miguel A., Hatten, Jeff A., Wheatcroft, Robert A., and Borgeld, Jeffry C.
Abstract:: We investigated the export of particulate organic matter (POM) to the ocean by two contrasting small, mountainous rivers, the Umpqua and Eel Rivers, by collecting suspended sediment samples over a range of discharges and analyzing them for a variety of constituents, including organic carbon, nitrogen, biomarkers with distinct biochemical sources,...

Characterization and spatial distribution of particulate organic matter in the Arctic Ocean

Creator:: Corvi, Elizabeth R.
Abstract:: Water samples from the Arctic Ocean were analyzed in order to assess the present nature of particulate organic matter and investigate the effect of climate-driven changes on the ecology of the region. 661 individual surface water samples and 216 samples from CTD casts were collected from the Bering, Chukchi, and...

Analysis of particulate organic matter distribution along surface waters of the California Current

Creator:: Welch, Kylie
Abstract:: Water samples along the Washington, Oregon and California coastline were collected using high resolution sampling and analyzed to determine particulate organic carbon and nitrogen concentrations. Over 28 days during August 2011, nearly 1500 samples were collected aboard the R/V Wecoma (W1108C) using a semi-automated filtration system. Additional subsurface samples were...
