1. 1. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

   University essay from Umeå universitet/Institutionen för fysik

   Author : Klara Lindroth; [2023]
   Keywords : automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

   Abstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE

3. 2. Simulation based optimizing of fog mesh structures for enhanced fog collection

   University essay from KTH/Teknisk mekanik

   Author : Jiawei Miao; [2022]
   Keywords : ;

   Abstract : Water scarcity has been an increasing problem in many places around the world. According to the World Resources Institute, in 2019 nearly 2.6 billion people which takes a third of the world's population live in the area with 'high water scarcity', with 1.7 billion people in 17 countries living under 'extreme water scarcity'.

4. 3. CFD investigation of Plate Channels

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Anton Johannesson; [2022]
   Keywords : Plate Heat Exchanger; Turbulence modelling; Generalized k-omega; GEKO; CFD; Computational Fluid Dynamics; Technology and Engineering;

   Abstract : Alfa Laval has a wide product range for plate heat exchangers that can be applied in most industries. The constant development of new and old heat exchangers drive the need for new and efficient methods that can reliably be used in the development process. READ MORE

5. 4. Investigation on Operation of the Compact Molten Salt Reactor by Modelling the Primary Circuit in GeN-FOAM

   University essay from KTH/Fysik

   Author : Jelle Oving; [2022]
   Keywords : molten salt reactor; GeN-Foam; delayed neutrons; OpenFOAM; multi-physics; smältsaltreaktor; GeN-Foam; fördröjda neutroner; OpenFOAM; multifysik;

   Abstract : In recent years there has been a revision of the molten salt nuclear reactor concept for production of power. Moving of fissile material throughout the primary circuit for these types of reactors creates the necessity of novel physics solvers to study movement of delayed neutron precursors, plant operation, accident scenario's; crucial for design.

6. 5. 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
