1. 1. Development and validation of an improved wall-function boundary condition for computational aerodynamics

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Carlo Loris Palombo; [2021]
   Keywords : Wall Functions; Wall Treatment; M-Edge; Computational Fluid Dynamics; Turbulent Boundary Layer; Turbulence Models; Väggfunktionsranvillkor; M-Edge; Strömningsmekaniska beräkningar; Turbulent Gränsskikt; Turbulensmodeller;

   Abstract : Computational Fluid Dynamics is a powerful and widely used tool for developing projectsthat concern flow motion, in very different fields. Industrial CFD solvers are continuouslydeveloped with the aim of improving accuracy and reducing the computational cost of thesimulations. READ MORE

3. 2. Simulating flow-noise for after-treatment systems

   University essay from KTH/Teknisk mekanik

   Author : Adam Sandström; [2020]
   Keywords : Flow-noise; CAA; DES; non-refelctive boundary conditions; stretched grid; Menter SST;

   Abstract : Modern silencers for heavy vehicle applications are designed to cancel out the sound generated by the effects of combustion and propagation of exhaust gases through the engine after-treatment system. The complex geometry within the compact silencer give rise to self generated (or flow-) noise that contribute to the total sound power radiated at the exhaust outlet. READ MORE

4. 3. Efficient seakeeping performance predictions with CFD

   University essay from KTH/Marina system

   Author : Benjamin Lagemann; [2019]
   Keywords : added wave resistance; CFD; Courant-adapted time step; Euler ˛flow; FINE Marine; inviscid flow; k-ω SST-Menter; KVLCC2; RANS; regular waves; seakeeping; sub-cycling acceleration; time discretization; viscous flow;

   Abstract : With steadily increasing computational power, computational fluid dynamics (CFD) can be applied to unsteady problems such as seakeeping simulations. Therefore, a good balance between accuracy and computational speed is required. READ MORE

5. 4. Improving Aerodynamic Performance of a Truck: a Numerical Based Analysis

   University essay from KTH/Mekanik

   Author : Johan Malmberg; [2015]
   Keywords : ;

   Abstract : With a change in EU-legislation regarding the dimensions of heavy trucks [1] coming up, specifically allowing aerodynamic devices fitted to the back of trailers, the transportation industry is set to largely decrease its environmental impact in the near future. These aerodynamic devices have been researched for quite some time [2] but have not yet gained widespread market acceptance, partly because of the transportation industry’s complex owner structures and partly because of size regulations of the past.
