1. 1. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Sergi Tarroc Gil; [2021]
   Keywords : Zonal Model; Thermal Comfort; Fluid Simulation; Aircraft Cabin Design; NURBS; Morphing; Radial Basis Functions; Meshing; Co-located Mesh; Unstructured Mesh; Mesh Quality; Mesh Smoothing; Enlarged Orientation Theorem; Fractional Step Method; Boussinesq; Adam Bashforth; Helmholtz-Hodge Theorem; Rhie and Chow; Difference Schemes; Gradient Evaluation; Differential Heated Cavity; Driven Cavity; Draught Rate;

   Abstract : The simulation of physical systems in the early stages of conceptual designs has shown to be a key factor for adequate decision making and avoiding big and expensive issues downstream in engineering projects. In the case of aircraft cabin design, taking into account the thermal comfort of the passengers as well as the proper air circulation and renovation can make this difference. READ MORE

3. 2. 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.

4. 3. 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

5. 4. 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

6. 5. 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
