16. Simulations of complete vehicles in cold climate at partial and full load driving conditions
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : In this study, CFD simulations of a complete truck are carried out to investigate the effect of altered simulation settings at cold climatic conditions. The aim of this study is to obtain knowledge through CFD simulations performed on a selected driving condition namely at a vehicle speed of 93 kph, an ambient temperature of -20 °C and for an engine operating at 25 % load.

17. Aerodynamic Design in Axial Turbine for Heavy Duty Applications
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Turbomachinery design is based on multiple physical thermodynamical relations and fluid mechanics. Software implementing these relations in computing fluid flows have been broadly accessible since the 1990’s and has also become more applied to turbomachinery design. LÄS MER
18. Parametric Adjoint Optimization of a Twisted Rudder
Master-uppsats, KTH/Marina systemSammanfattning : Optimization methods are commonly used to develop new products and are also an importantstep in more incremental design improvements. In the maritime industry, these methodsare often used to create more ecient vessels and to ful ll the environmental requirementsimposed by the IMO. In recent years, the adjoint method have been used more frequently. LÄS MER
19. Venturi Undertray : KTH Bachelor Thesis Report
Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : 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.

20. Implementation, Validation, and Evaluation of 1D-3D CFD Co-simulation for Cooling System of Internal Combustion Engine
Master-uppsats, KTH/FordonsdynamikSammanfattning : Internal combustion engines, electric motors and batteries generate a significant amount of heat during operation that needs to be extracted by cooling systems. A cooling system is designed and installed to extract the generated heat and maintain the system temperature in an optimal range. LÄS MER
