Large-eddy simulation of turbulent channel flow using the explicit algebraic subgrid-scale model

Large-eddy simulation (LES) of turbulent channel flow are performed with a new subgrid-scale (SGS) stress model. The simulations show that with this model we can well predict turbulent wall flows at coarse resolutions and moderately high Reynolds numbers. The commonly used dynamic Smagorinsky model fails at coarser resolutions.

Explicit algebraic and differential Reynolds stress model application to homogeneously sheared and compressed turbulence

An explicit algebraic and differential Reynolds stress models (EARSM and DRSM) are used to investigate the influence of homogeneous shear and compression on the behaviour of turbulence in the limit of rapid distortion theory (RDT). EARSM is shown to give realizable results and to preserve RDT regime, unlike the eddy-viscosity model (EVM). The...

Construction an arena for energy efficient multi-family housing development: A case study of inter-organisational knowledge sharing

The Swedish building sector has for a long time struggled with the difficulty to create and share new knowledge. Within the sector, groups of professionals have been found to only share knowledge with members of their network, not with those they consider to be outsiders. As an attempt to unite different views and professional groupings, an...

Landfill mining: A review of three decades of research

Landfills have historically been seen as the ultimate solution for storing waste at minimum cost. It is now a well-established fact however that such deposits have related implications such as long-term methane emissions, local pollution concerns and limitations on urban development. Landfill mining has been suggested as a strategy to address...
