1. Methodologies for RANS-LES interfaces in turbulence-resolving simulations
Sammanfattning : Hybrid Reynolds-Average Navier-Stokes (RANS)-Large-Eddy Simulations (LES) techniques are now seen by the aeronautical industry as the most promising turbulence-resolving approaches for complex high-Reynolds-number turbulent flows with regard to cost and accuracy. However, connecting RANS and LES simulated flows is a challenging task and needs special attention in order to increase simulation robustness and accuracy. LÄS MER
2. A body force method for high precision offshore wake modelling simulations
Sammanfattning : .... LÄS MER
3. CFD Modelling of Hydrogen Rich Biomass Syngas Combustion
Sammanfattning : The loss of biodiversity, due to pollution and global warming, is more important and relevant now than it has ever been. Man made climate warming has its roots in the huge amount of CH4 and CO2 emissions, which have increased by 47% and 156% respectively since 1750. LÄS MER
4. Predicting flow-generated noise from HVAC components
Sammanfattning : More energy efficient fans, i.e. larger sizes running at lower speeds, in Heating Ventilation and Air Conditioning (HVAC) systems decrease the fan noise and increase the importance of flow generated noise in other system components, e.g. LÄS MER
5. Numerical Investigation of Unsteady Crosswind Aerodynamics for Ground Vehicles
Sammanfattning : Ground vehicles are subjected to crosswind from various origins such as weather, topography of the ambient environment (land, forest, tunnels, high bushes...) or surrounding traffic. LÄS MER
