15 صفحه اولStatistics of temperature fluctuations in a buoyancy dominated boundary layer flow simulated by a Large-eddy simulation model
Temperature fluctuations in an atmospheric convective boundary layer are investigated by means of Large Eddy Simulations (LES). A novel statistical characterization for both weak temperature fluctuations and strong temperature fluctuations has been found. Despite the nontriviality of the dynamics of temperature fluctuations, our data support the idea that the most relevant statistical propertie...
متن کاملLarge-eddy Simulation of a Particle- Laden Turbulent Channel Flow
Large-eddy simulations of a vertical turbulent channel flow with 420,000 solid particles are performed in order to get insight into fundamental aspects of a riser flow. The question is addressed whether collisions between particles are important for the flow statistics. The turbulent channel flow corresponds to a particle volume fraction of 0.013 and a mass load ratio of 18, values that are rel...
متن کاملLarge-eddy simulation of large-scale structures in long channel flow
We investigate statistics of large-scale structures from large-eddy simulation (LES) of turbulent channel flow at friction Reynolds numbers Reτ =2K and 200K (where K denotes 1000). In order to capture the behaviour of large-scale structures properly, the channel length is chosen to be 96 times the channel half-height. In agreement with experiments, these large-scale structures are found to give...
متن کاملLarge-eddy simulation of particle-laden channel flow
Large-eddy simulation of particle-laden turbulent channel flow is investigated for several subgrid models and Stokes numbers with the objective to investigate the accuracy of the subgrid models studied with respect to particle behavior. It is shown that the wall-normal particle velocity and particle velocity fluctuations are reduced compared to DNS, if the filtered fluid velocity calculated in ...
