  1. 1. 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

  3. 2. On the Design of a Reactor for High Temperature Heat Storage by Means of Reversible Chemical Reactions

    Master-uppsats, KTH/Energiteknik

    Författare :Patrick Schmidt; [2011]
    Nyckelord :Thermo-chemical Storage; Gas-Solid Reaction; High Temperature; Calcium Hydroxide; Reactor Concept; Modelling;

    Sammanfattning : This work aims on the investigation of factors influencing the discharge characteristicsof a heat storage system, which is based on the reversible reaction system of Ca(OH)2and CaO. As storage, a packed bed reactor with embedded plate heat exchanger forindirect heat transfer is considered. LÄS MER

  4. 3. COMPUTATIONAL ANALYSIS OF GAS SOLID FLOW IN A PNEUMATIC DRYER

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Författare :Gao Feng; Adelere Oluwafemi. A.; [2008]
    Nyckelord :Finite volume method FVM ; SIMPLE method; Straight pipe dryer; Screw type dryer; MATLAB®; GAMBIT®; FLUENT;

    Sammanfattning : This work presents a design of drying small food particles like tea, tobacco with a reduced height of about fifty percent compared to the convectional straight type. The geometry is designed such that, the particle leave the dryer at an average constant time, to prevent variation in the dryness properties, Simulation result of straight type dryer in FLUENT, the commercial software is validated by industrial data implemented in MATLAB, which shows reasonable agreement.
