3. 2. Wading Simulations of Complete Heavy-Duty Vehicles

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Emma Samuelsson; Sofie Benzler; [2022]
   Keywords : CFD; Volume of Fluid; Wading; Heavy-Duty Vehicles; STAR-CCM ;

   Abstract : Wading is the phenomenon where a vehicle drives through water with a relatively deep water level. Sincea large portion of the vehicle is submerged in water it can affect the driveability and function of individualcomponents. READ MORE

4. 3. CFD Analysis of Water Replenishment Holes in an Offshore Wind Turbine Foundation

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Shubham Arvind Tupkar; Swetha Sappe Narasimhamurthy; [2022]
   Keywords : CFD; Wave Dynamics; Implicit LES; GABC; OpenFOAM; Stokes V; Monopile Foundation; Replenishment Holes;

   Abstract : The study presented in this thesis investigates the passive exchange of enclosed water with seawater in an offshore wind turbine foundation. This thesis was undertaken in collaboration with Vattenfall R&D, Älvkarleby, Sweden. The water exchange is studied by utilizing Computational Fluid Dynamics (CFD) simulations. READ MORE

5. 4. Analytical Investigation of Planetary Gears Instabilities and the Impact of Micro-Macro Geometry Modifications

   University essay from KTH/Farkostteknik och Solidmekanik

   Author : Hamza Oudich; [2020]
   Keywords : Planetary gears; Instabilities; Resonance; Vibration; dynamic response; Spectral Iterative Method; Modal analysis; Static and dynamic transmission error; Gear mesh stiffness; Macro and micro-geometry; Phasing;

   Abstract : Due to their large torque-speed ratio and transmission efficiency, planetary gears are widely used in the automotive industry. However, high amplitude vibrations remain their critical weakness, which limits their usage especially when new strict noise legislations come into action. READ MORE

6. 5. Modelling of Whiplash Trauma Parametric study of rear-end impacts using FEM and CFD

   University essay from

   Author : Andreu Oliver González; Mourya Vanama; [2019-07-03T12:20:01Z 2019-07-03T12:20:01Z 2010]
   Keywords : Farkostteknik; Strömningsmekanik; Vehicle Engineering; Fluid mechanics;

   Abstract : This work is a combination of Finite Element (FE) modelling and Computational Fluid Dynamics (CFD) to investigate the effect of acceleration pulses, head restraint and seating posture on facet joint loads and pressure transient magnitudes on the neck injury outcome during whiplash motion. A parametric study is carried out with the FE human body model THUMS (Total HUman Model for Safety) for a variety of crash pulses and crash conditions that have a known relative risk of long term neck injuries in rear-end impacts.
