  1. 1. Development and Analysis of a Gaseous Hydrogen-Oxygen Rotating Detonation Combustor

    University essay from KTH/Kraft- och värmeteknologi

    Author : Birgir Steinn Hermannsson; [2022]
    Keywords : ;

    Abstract : Theory suggests that more efficient rocket propulsion can possibly be achievedby utilizing a pressure-gain detonative combustion process instead of conventional deflagration combustion. To demonstrate this, rotating detonation engines that sustain one or several detonation waves in an annular enclosure havebeen a subject of research for decades. READ MORE

  3. 2. CFD Annular Flow Modelling Based on a Three-Field Approach

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Erik Skoog; [2020]
    Keywords : CFD; BWR; annular flow; deposition;

    Abstract : This master thesis aim to model the annular flow that occurs in the final section between the fuel rods inside Boiling Water Reactors, by approximating the geometry to a cylindrical pipe. Simulations were performed in the software ANSYS Fluent, as a step in the development of replacing the 1D correlations currently used in the nuclear industry with CFD models in 3D. READ MORE

  4. 3. Experimental validation of a periodic heat transfer CFD model of a vertical shell and tube heat exchanger

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Patrik Bengtsson; Dilip Kumar Vellore Saikumar; [2019]
    Keywords : ;

    Abstract : Flow obstructions are used as a passive design element in heat exchangers to enhance heattransfer. Further, a change in flow structure can also have a positive effect on the heat transfer. Avertical shell and tube heat exchanger, used to recover heat in the greywater stream, isinvestigated in this study. READ MORE

  5. 4. Numerical Investigation of Various Modelling Strategies for Throttling a Transonic Compressor Rig Diffuser

    University essay from KTH/Kraft- och värmeteknologi

    Author : Borzou Dargahi; [2019]
    Keywords : ;

    Abstract : The concern of this study is modeling of the flow field in the diffuser of a 1.5 stage compressor test rig in which the mass flow is constrained at the exit of the diffuser. Constraining method is is applied through, throttling by means of a slab at the exit of the diffuser, where the flow enters the exit volute. READ MORE
