  1. 1. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Jean-Pierre Hamzo; [2023]
    Keywords : CFD; gas-turbine; computational fluid dynamics; atomizer; prefilmer; RANS; LES; multi-phase; experimental; numerical; atomization; spray characteristics; drop breakup; liquid fuels; liquid films;

    Abstract : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. READ MORE

  3. 2. Mathematical modelling of Degussa Furnace

    University essay from KTH/Materialvetenskap

    Author : Rans Faraydoun Muhammed; [2021]
    Keywords : Furnace; CFD; ANSYS; Thermodynamic model; Exchange time; Ugn; CFD; ANSYS; Termodynamisk model; Utbytestid;

    Abstract : The energy demands in the world is rapidly increasing and with this,  a supply nuclear  power  is  of  much  interest.    Nuclear  fuel  is  relatively  efficient  when comparing to power sources like wind­ and hydropower plants. READ MORE

  4. 3. CFD Simulation of a Fin-Tube Evaporator under icing

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Abhay Mahesh Hervatte; [2021]
    Keywords : CFD; Refrigeration; HVAC; Evaporator; Thermodynamics; Icing;

    Abstract : The study involves development of a methodology to simulate a fin-tube evaporator under icing conditions using CFD in Ansys® Academic Fluent 2021R1. It aims to build on previous studies performed on heat pumps. It was performed by Abhay M. Hervatte in collaboration with Bosch Thermoteknik AB, Tranås, SE during the spring term of the year 2021.

  5. 4. Cavitation analysis on test rig. : An experimental and CFD study executed in collaboration with Epiroc AB

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Oskar Kuoppala; [2021]
    Keywords : CFD; Cavitation; Water Hammer;

    Abstract : This master thesis project was done in collaboration with Epiroc Group Ab. Epiroc supplies high-quality drills of various types that can be used both above and below ground. A major problem in their percussive rock drills is that that cavitation is formed. Cavitation is a phenomenon that occurs when a fluid is subject to a sudden pressure drop. 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
