    Computational and experimental representation of simplified gas turbine bearing chamber geometries by Ahmad H. Attia, Budi Chandra, C.A. Toomer

    Published 2025-03-01
    “…However, achieving a uniform oil coating on bearings remains a challenge, often leading to excessive oil consumption and in-flight oil loss. This research aims to establish accurate experimental and CFD methods to measure the residence time distribution (RTD) in a simplified linear geometry, progressing towards investigations in a cylindrical bearing chamber rig.The first test case uses an inclined rectangular acrylic channel (140 cm length, 3 cm height, 5 cm width) with a 39° slope and flow rates ranging from 0.9 l/min to 2.7 l/min. …”

    Collapsibility of Gypseous Soil Treated with Pectin-Biopolymer through Leaching by Ahmed H. Hussein, Farouk M. Muhauwiss, Riyadh A. Abdul-Jabbar

    Published 2023-01-01
    “…The danger increases when water flows through it and works to leach the soil, which leads to the loss of its mass by leaching gypsum. The soil is chemically and mechanically improved to enhance its geotechnical properties, but despite its great advantages in strengthening, it has significant negative effects on the ecosystem, so the use of environmentally friendly materials is essential. …”
