  1. 1. Spatio-temporal analysis of groundwater-dependent precipitation based on Lagrangian moisture tracking

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Daowei Li; [2022]
    Keywords : Groundwater abstraction; groundwater dependent precipitation; ERA5 precipitation; Utrack; Lagrangian model.;

    Abstract : Groundwater abstraction for irrigation use has steadily increased over the past decades, resulting in additional evaporation to the atmosphere, and increased precipitation. The precipitation stemming from groundwater irrigation (or Groundwater-dependent precipitation) has received little attention during recent years and is solely researched by the Eulerian model.

  3. 2. Wetland Precipitationsheds : Assessing the Potential Vulnerability of 40 RAMSAR Wetlands to Upwind Land Cover and Hydroclimatic Change

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Simon Felix Fahrländer; [2022]
    Keywords : Wetlands; precipitationsheds; moisture import; moisture tracking; Lagrangian moisture tracking; land-atmosphere feedback;

    Abstract : Wetland ecosystems play an important role in the global hydrologic cycle, and their hydrologicregime is a major factor for their general functioning (carbon, biodiversity, biogeochemicalcycle etc.). READ MORE

  4. 3. LES modelling of spray combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Arvid Åkerblom; [2021]
    Keywords : Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

    Abstract : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

  5. 4. Study of flow fields in mixing tanks with particles using CFD

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Sergio Poveda Ruiz; [2021]
    Keywords : Keywords: Solid-liquid mixing; particle suspension; aseptic tanks; stirrer geometries; flow fields; URANS; particle modeling; LPT; DEM.; Technology and Engineering;

    Abstract : The demand for food products with particles has increased in the last decades. Among them, yoghurt with fruit pieces or cereals can be found. Thus, the food processing industry is facing important challenges to offer these products to meet the quality requirements. READ MORE

  6. 5. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow

    University essay from Uppsala universitet/Signaler och system

    Author : Simon Wredh; [2020]
    Keywords : computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

    Abstract : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. READ MORE
