1. 1. The Race to Success: Navigating the Roadblocks to Formula E's Popularity

   University essay from Lunds universitet/Företagsekonomiska institutionen

   Author : Rebecca Aharon; Fu Jill Dakota van der Horst; Guillaume Berge; [2023]
   Keywords : Keywords: Brand loyalty; Corporate Brand Identity; Sustainable Messaging; Media Influence; Business and Economics;

   Abstract : Purpose: Formula E, the electric counterpart to Formula 1, has not achieved the same level of popularity among consumers. The purpose of this paper is to understand why Formula E has not been as successful as Formula 1 and the barriers to consumer adoption of Formula E. READ MORE

3. 2. Improving the Robustness, Thermal and Noise Performance of a Radio Transmitter Fan Tray

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Mattias Olausson; Selma Rahman; [2022]
   Keywords : Fan tray; Heat dissipation; Robustness; Radio transmitter; Noise performance; Fläktlåda; Värmeavledningsförmåga; Robusthet; Radio sändare; Ljudprestanda;

   Abstract : With the growing demand of compact radio transmitters, so do the need for silent and efficient thermal management systems. Given the restricted form-factor, ensuring robustness of a unit with a detachable fan tray imposes a challenge. READ MORE

4. 3. Experimental Study of Installation Effects on Cooling Fan Noise

   University essay from KTH/Marcus Wallenberg Laboratoriet MWL

   Author : Yu-Yu Lu; [2021]
   Keywords : Electric vehicles; Cooling fan noise; Installation effects; Free-space measurement; Wall-mounted measurement; In-vehicle measurement; Spectral decomposition method; Tonality; Broadband noise level.;

   Abstract : Owing to the ever-changing developments of battery and electric powertrain, vehicle electrification is the trend in the future. Without the presence of a combustion engine, masking effect from it reduces and noises from other components become perceivable. Among all, the cooling fan is one of the major noise sources.

5. 4. A Numerical Approach for Wind Tunnel Noise Control

   University essay from KTH/Marcus Wallenberg Laboratoriet MWL

   Author : Hampus Dall; Robert Palm; [2021]
   Keywords : Technical Acoustics; ANC; Active Noise Control; Superposition; Wind Tunnel; Wingsuit; Indoor Wingsuit; Higher Order Modal Acoustic Field Beyond Plane Wave Region; Numerical Acoustic Simulations; Teknisk Akustik; Aktiv Brusreducering; Superposition; Vindtunnel; Flygning med ekorrdräkt inomhus; Högre ordningens akustisk modanalys bortom planvågsteori; Numeriska akustiska simuleringar;

   Abstract : A wind tunnel from the 1950s located in Bromma, Stockholm, once used for military research is today used for commercial activities. Today the tunnel is used for indoor wingsuit flight and the facility has an interest in reducing the overall noise generated by the tunnel. Acoustic measurements indicate noise problems in the 50 Hz range. READ MORE

6. 5. 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
