1. 1. Turbulent Boundary Layers Modelling with Deep Operator Networks

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Yu-Cheng Lu; [2023]
   Keywords : Turbulent Boundary Layers; Pressure Gradient; Composite Profiles; Deep Operator Networks; Sensitivity Analysis Nyckelord på svenska;

   Abstract : This thesis project aims to advance the modelling of pressure gradient turbulent boundary layers (PG TBLs) and offer new insights into TBLs modelling. Previous analytical studies have explored various mathematical models, but this research introduces an extended unstacked Deep Operator Networks (DeepONets) architecture with double outputs and five branch parameters.

3. 2. Air Cooling of Lithium Polymer Batteries : Experiments and Calculations on the KTH Formula Student 2022 Race Car Accumulator

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : William Olsson; Linus Grinde; [2022]
   Keywords : ;

   Abstract : Lithium batteries work optimally at a temperature of around 15 to 35 °C, with a maximum temperature of around 60 °C. To get the most performance out of a formula student car the cooling needs to keep the battery cells within these temperatures during the competition. READ MORE

4. 3. Design of compact automotive heat exchanger, analysing the effects of RANS models and utilising Additive Manufacturing

   University essay from KTH/Fysik

   Author : Nikhil Srikkanth; Bartosz Brzuchalski; [2022]
   Keywords : Turbulence; Reynolds Averaged Navier-Stokes; KTH Formula Student; metal additive manufacturing; CFD; turbulent kinetic energy; boundary layer;

   Abstract : The analytical modelling of complex turbulent airflow remains one of the great unsolved mysteries of physics, but in this paper two widely used Reynolds Averaged Navier-Stokes models (k-$\epsilon$ and k-$\omega$ SST) are compared while designing a heat exchanger for the KTH Formula Student electric race car. CAD software was used to design lattices for the heat exchanger core and theorise about how to increase heat transfer while also taking into account the utilisation of metal additive manufacturing.

5. 4. Gone With the Headwind. Characterizing Erosion Using Lattice-Boltzmann Method : and its Implication in Planet Formation

   University essay from Stockholms universitet/Fysikum

   Author : Lukas Cedenblad; [2019]
   Keywords : Erosion; Planet formation; Lattice-Boltzmann;

   Abstract : Erosion has a long history in science and is used in many different fields today, for example in geology for coastal erosion and in the oil industry for pipe erosion. It is very difficult to study erosion both analytically. Numerically it is difficult due to moving and shape-changing boundaries. READ MORE

6. 5. Analytical prediction of turbocharger compressor performance: A comparison of loss models with numerical data

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Sergio Sanz Solaesa; [2016]
   Keywords : ;

   Abstract : One-dimensional models predict the performance of centrifugal compressor in short time, being a helpful design tool in the early design stages. They assume uniform flow through the compressor. Conservation of mass, momentum and energy and some empirical loss correlations are applied to estimate the real outputs. READ MORE
