1. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : 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. LÄS MER
2. Unstructured mesh adaptation for turbo-machinery RANS computation
Master-uppsats, KTH/FlygdynamikSammanfattning : 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.

3. Aerodynamic performance of a wind-turbine rotor by means of OpenFOAM
Master-uppsats, KTH/MekanikSammanfattning : 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. LÄS MER
4. Simulation and data analysis of peer-to-peer traffic for live video streaming
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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. LÄS MER
5. Implementation of k-Exact Finite Volume Reconstruction in DLR’s Next-Generation CFD Solver: Flucs and its Comparison to Other Methods
Master-uppsats, KTH/MekanikSammanfattning : 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. LÄS MER
