Large eddy simulation using the general circulation model ICON

Temperature simulation of southwestern Iran during (2015-2050) using data from the general air circulation model

In recent years, global warming and climate change have been associated with dire consequences for human societies. Changes in climate patterns can lead to severe floods, extreme heat and cold, more frequent droughts, and global warming. This increase in global warming has upset the Earthchr('39')s climate balance and caused widespread climate change in most parts of the world, known as climate...

Large-eddy Simulation Using the Stretched-vortex Sgs Model

Large-eddy simulations of decaying turbulence and turbulent channel ow using the stretched-vortex subgrid-stress model are presented and discussed. In the stretched-vortex model, the subgrid turbulence is assumed to consist of vortices whose orientations are determined by the resolved velocity eld. This, combined with a relationship connecting the subgrid stresses to the vortex-structure orient...

Large eddy simulation of turbulent channel flows by the rational large eddy simulation model

Mixed Large-Eddy Simulation Model for Turbulent Flows across Tube Bundles Using Parallel Coupled Multiblock NS Solver

In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...
