  3. 2. Numerical evaluation of the ground vortex

    University essay from KTH/Teknisk mekanik

    Author : Martin Babo; [2022]
    Keywords : Turbofan engine; CFD; Flow simulation; Ground Vortex; External aerodynamics;

    Abstract : This master thesis covers the realization of a CFD calibration study regarding the numerical simulation of the ground vortex phenomenon. As part of InVIGO project (EU CleanSky2), wind tunnel test campaigns were performed using a nacelle model combined with a movable raised floor. READ MORE

  4. 3. Development of a CFD Boundary Condition to Simulate a Perforated Surface

    University essay from Umeå universitet/Institutionen för fysik

    Author : Medet Kiflemariam; [2021]
    Keywords : Computational Fluid Dynamics; CFD; Boundary Condition; Bleed; Aerospace Engineering; Aeronautical Engineering; Physics;

    Abstract : In aircraft with jet propulsion engine intakes at supersonic speed, strong pressure waves referred to as shockwaves occur, which may interact with any present boundary layers along the intake surface. The adverse pressure gradients associated with Shock Wave-Boundary Layer Interaction (SWBLI) may cause boundary layer flow separation, which can result in disturbances of the flow that can be harmful to the device or decrease engine performance.

  5. 4. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Bhargav Reddy Elavarthi; [2021]
    Keywords : micropollutants; activated carbon filtration; empty bed contact time EBCT ; pharmaceuticals; breakthrough curves; adsorption; PFOS; carbon use; water and environmental engineering; Technology and Engineering;

    Abstract : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. READ MORE
