Investigations of Three- Dimensional Turbulent Cavity Flow Using Large Eddy Simulation Approach

Underground Fire Rollback Simulation in Large Scale Ventilation Models

A feasible solution is to create a single network model to simulate both the large scale ventilation model and the smaller scale rollback behavior. This can potentially be achieved by creating a detailed high density three-dimensional mesh of pathways bounded by the airway around a fire which then feeds into the simpler network of a large scale ventilation model. The high density mesh allows a ...

Study of natural ventilation in buildings by large eddy simulation

Natural ventilation in buildings can create a comfortable and healthy indoor environment, and can save energy used in the mechanical ventilation systems. Two subgrid-scale models of large eddy simulation (LES), a Smagorinsky subgrid-scale (SS) model and a Filtered dynamic subgrid-scale (FDS) model, have been used to study airflow in buildings with natural ventilation. It was found that, for ful...

Large Eddy Simulation of dispersed multiphase flow

This thesis covers two main topics. The first is the comparison between the Reynoldsaveraged Navier-Stokes (RANS) simulation and the Large Eddy Simulation (LES) of high injection pressure diesel sprays under non-evaporating or evaporating conditions. The second topic is the comparison of the fuel behavior in the spray process between the hydrotreated vegetable oil (HVO) and the conventional EN ...
