1. 26. Exterior water flow simulation

   Master-uppsats, Lunds universitet/Innovation

   Författare :Daniel Persson; Erik Nilvé; [2018]
   Nyckelord :CFD; Fluid Mechanics; Product Development; Simulation; Water Flow; Technology and Engineering;

   Sammanfattning : The Water Tightness group at Volvo Cars is responsible for creating and maintaining requirements and thresholds regarding water flows on a car. This is performed by doing extensive physical testing while making sure that databases and previous requirements are kept up to date. LÄS MER

5. 29. CFD analysis of stepped planing vessels

   Master-uppsats, KTH/Mekanik

   Författare :Toni Kokkonen; [2018]
   Nyckelord :Computational Fluid Dynamics CFD ; Ship hydrodynamics; Planing hull; Stepped hull; STAR-CCM ; Overset mesh; Volume of fluid VOF ; Reynolds averaged Navier-Stokes equations RANS ; Dynamic instabilities;

   Sammanfattning : High speed planing hulls are currently widely used for example in recreational and emergency vessel applications. However, very little CFD research has been done for planing vessels, especially for those with stepped hulls. A validated CFD method for planing stepped hulls could be a valuable improvement for the design phase of such hulls. LÄS MER

7. 30. CFD-simulations of urea-waterspray in an after-treatment systemusing Star-CCM+

   Master-uppsats, KTH/Mekanik

   Författare :Emelie Trigell; [2018]
   Nyckelord :after-treatment systems; selective catalytic reaction SCR ; AdBlue; multiphase flow; multi-component liquid; Unsteady Reynolds Average Navier Stokes RANS ; wall film formation; solid deposits; efterbehandlingssystem; selektiva katalytiska reaktioner; AdBlue; flerfasstr ¨ommning; flerkomponentvätska; Unsteady Reynolds Average Navier Stokes; väggfilm; avlagringar;

   Sammanfattning : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. LÄS MER
