1. 6. 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.

3. 7. Undertray Design and Development Procedure with CFD : An Optimization Study of Different UndertrayDesigns with CFD Computations

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Aaron Poutiainen; [2021]
   Keywords : ;

   Abstract : Race car aerodynamics has played a vital part to improve lap times over the years of motor racing. Having good road adhesion with slick tires and aerodynamic downforce will increase the vehicles maximum lateral force and thus higher cornering speeds can be achieved. READ MORE

4. 8. Shape optimization of axial cooling fan via 3D CFD simulation and surrogate modeling

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Martin Granlöf; [2021]
   Keywords : Fan noise; shape optimization; mesh morphing; computational fluid dynamics; computational aeroacoustics; Efficient Global Optimization; Reynolds-averaged Navier-Stokes;

   Abstract : Due to legislative reasons and environmental concerns the automotive and transport sector are shifting their focus from traditional internal combustion engine (ICE) vehicles to development of battery electric vehicles (BEVs). This brings new challanges to design of cooling systems where axial fans are one of the key components. READ MORE

5. 9. Venturi Undertray : KTH Bachelor Thesis Report

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

   Author : Selma Boudali; Mattias Olausson; [2020]
   Keywords : Race car aerodynamics; undertray; Venturi effect; Formula student; CFD analysis; Topology optimization.; Aerodynamiken på racerbil; underrede; Venturi effekt; CFD analys; Topologioptimering.;

   Abstract : This bachelor thesis aims to describe the work performed for the design of the undertray for the Kungliga Tekniska Högskolan Formula Student(KTHFS) race car. The goal was to achieve an aerodynamically optimized undertray design that follows the regulations of the competition and the targets set by KTHFS concerning the weight, the size, the materials needed for its manufacture and costs.
