1. 1. Development of CAD Models for Large Silencer Platforms Using Design Automation

   Master-uppsats, Linköpings universitet/Produktrealisering

   Författare :Mahim Kai; Balagangadar Thilakar Arumugam; [2023]
   Nyckelord :Design Automation; Silencer; CFD; Extraction;

   Sammanfattning : Scania is known as a front-runner in the development of power trains for heavy vehicles, marine, and general industrial applications. As the regulations on emissions for combustion engine vehicles are getting tougher with increasing awareness on sustainable solutions and reducing environmental impact, the goal at Scania is to develop combustion engines to achieve low-pollutant emissions whilst achieving higher efficiency.

3. 2. CFD investigation of a unit cell inside a Plate Heat Exchanger

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Mattias Ly; [2023]
   Nyckelord :Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

   Sammanfattning : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. LÄS MER

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

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

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

   Sammanfattning : 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. LÄS MER

5. 4. 3D CFD Simulations of Hydrogen Engine Combustion

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Hao Liu; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : With the trend of decarbonization, the transport sector is exploring possibilities of fossil fuel free solutions. Hydrogen can be a potential fuel for future engine applications. In this work, the concept of H2 HPDI is investigated, where a pilot diesel injection ignites the hydrogen jet. LÄS MER

7. 5. CFD Simulations of Velocity and Temperature Distributions of the AuraGen Axial Flux Machine

   Master-uppsats, KTH/Maskinkonstruktion (Inst.)

   Författare :Huanyu Chen; [2022]
