  1. 1. Unstructured mesh adaptation for turbo-machinery RANS computation

    University essay from KTH/Flygdynamik

    Author : Marc-Antoine Bouvattier; [2017]
    Keywords : Metric tensor; mesh adaptation; anisotropy; projection error; turbo-machinery; unstructured mesh; Riemannian;

    Abstract : This paper gives an overview of the mathematical and practical tools that can be used in turbo-machinery RANS simulation to realize unstructured mesh adaptation. It first presents the concept of metric and recalls that the hessian of the physical flow properties can become, thanks to small modifications, both a metric and a upper bound of the P1 projection error.

  2. 2. Aerodynamic performance of a wind-turbine rotor by means of OpenFOAM

    University essay from KTH/Mekanik

    Author : Evangelos Giannopoulos; [2017]
    Keywords : wind turbine; rotor; performance; CFD model; boundary layer; roughness;

    Abstract : In order for wind-farm operators to deal with challenges regarding their fleet management, it is useful for them to estimate their units’ performance for different conditions. To perform such estimations, Computational Fluid Dynamics (CFD) may be used. READ MORE

  3. 3. Simulation and data analysis of peer-to-peer traffic for live video streaming

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Anthony Smith; Andreas Johansson Lindgren; [2017]
    Keywords : P2P; Peer-to-Peer; Hybrid Live Video Streaming System; Mesh-based-pull Approach; Unstructured Network; Simulation; Visualisation; Technology and Engineering;

    Abstract : Evaluating and testing changes or configurations to peer-to-peer systems or even understanding their behaviour can be complicated. One approach is to simulate a large peer-to-peer system and visualise the results. READ MORE

  4. 4. Implementation of k-Exact Finite Volume Reconstruction in DLR’s Next-Generation CFD Solver: Flucs and its Comparison to Other Methods

    University essay from KTH/Mekanik

    Author : SIDDHANT AGARWAL; [2017]
    Keywords : ;

    Abstract : This thesis extended the order of the reconstruction of state for convective fluxes used by Finite Volume (FV) algorithm in DLR’s next-generation CFD solver: Flucs, from constant and linear to quadratic and cubic. Two approaches for calculating derivatives were implemented in Flucs and some test cases were tried. READ MORE

  5. 5. MIKE 21 FM in Urban Flood Risk Analysis : A comparative study relating to the MIKE 21 Classic model

    University essay from KTH/Vattendragsteknik

    Author : Alexander Salmonsson; [2015]
    Keywords : MIKE 21; flexible mesh; urban flooding; flood modelling; hydraulics; cloudburst; MIKE 21; flexibelt mesh; urban översvämning; översvämningsmodellering; hydraulik; skyfall;

    Abstract : Due to recent summers’ amplified frequency in intense rainstorm events, so-called cloudbursts, in places of the world not normally prone to such extreme weather phenomena, interest has aroused amongst authorities regarding measures to address in order to minimize the devastating impact of the subsequent floods. Such measures include physical planning of the townscape in terms of avoiding water to pond in inappropriate places. READ MORE
