  1. 1. LES modelling of spray combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

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

    Sammanfattning : 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.

    Sammanfattning : 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. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Simon Wredh; [2020]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 4. CFD Simulation of Particles in Pipe Flow and Mixing Tank

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Aljaz Janic; [2020]
    Nyckelord :Multiphase flow; particles; TetraPak; mixing tank; pipe flow;

    Sammanfattning : This project aimed to investigate the capability of the STAR CCM+ software when predicting the flow with particles using Lagrangian Particle Tracking and Discrete Element Method. The first part pertained to rectangular channel flow, with ratio between height of the channel and particle diameter (2h/Dp ) of 15. LÄS MER

  5. 5. Transport of non-spherical particles in pipeflow with suction

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Emil Wångby; [2020]
    Nyckelord :Brownian motion; Non-spherical particles; Pipe flow;

    Sammanfattning : The interest of how small non-spherical particles transport behaviour when transported in pipe-flow is of large interest in a variety applications. This kind of theory have been used when studying composite manufacturing and how particles behaves in the human lungs. LÄS MER
