  1. 26. ON SIMULATING COMPRESSIBLE FLOWS WITH A DENSITY BASED SOLVER

    Master-uppsats, KTH/Mekanik

    Författare :Sathyanarayanan Chandramouli; [2016]
    Nyckelord :Coupled density based solver; High Pressure Turbine Nozzle Guide Vane;

    Sammanfattning : A coupled density based solver in the framework of foam-extend is used to perform simulations of transonic flows. The solver is based on an explicit and time-accurate algorithm and is coupled to a compressible Unsteady Reynolds-Averaged Navier-Stokes (URANS) and a Large Eddy Simulation (LES) module. LÄS MER

  3. 27. Numerical & physical modelling of fluid flow in a continuous casting mould : Flow dynamics studies for flexible operation of continuous casters

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Henrik Barestrand; Tobias Forslund; [2016]
    Nyckelord :numerical modelling; physical modelling; fluid flow; continuous casting; casting; mould flow; fluid dynamics; flexible operation of continuous casters; LES; DPM; large eddy simulation;

    Sammanfattning : The current demands on Swedish steel industry to produce low quantity batches of specialized products requires research on steel casting processes. There are several physical processes that need be taken into account for this problem to be viewed in full light such as thermal-processes, solidification and fluid dynamics. LÄS MER

  4. 28. CFD analysis of nozzle effect on jet formation

    Master-uppsats, KTH/Mekanik

    Författare :Mustafa GÜDÜCÜ; [2015]
    Nyckelord :;

    Sammanfattning : This project is concerned with CFD simulations of jets issued from elliptical nozzles. The investigated jet flow in this project is turbulent flow emanating from microscopic nozzles into a combustion chamber. LÄS MER

  5. 29. Reactive-Di usive Flow Inside Porous Medium

    Master-uppsats, KTH/Mekanik

    Författare :Peyman Olad; [2015]
    Nyckelord :;

    Sammanfattning : Understanding the reactive-di usive turbulent ow inside porous media is interesting in many applications. It could have geochemical applications such as describing the rock dissolution patterns in river beds or the e ect of riparian zones in nitrate attenuation. Other applications could be, e.g. LÄS MER

  7. 30. Computational Fluid Dynamics Unstructured Mesh Optimization for the Siemens 4th Generation DLE Burner

    Master-uppsats, KTH/Mekanik

    Författare :Dejan Koren; [2015]
    Nyckelord :CFD; Ansys; Fluent; CFX; Mesh optimization; DLE burner; Siemens; Mixing;

    Sammanfattning : Every computational fluid dynamics engineer deals with a never ending story – limitedcomputer resources. In computational fluid dynamics there is practically never enoughcomputer power. LÄS MER
