Three Problems in the Large-Eddy Simulation of Complex Turbulent Flows,pressible turbulent flows, (ii) uses numerical solutions of the RDT equations to suggest the possibility that the linear effects of pressure might be more important to model in the near-wall problem, than nonlinear transfer, and (iii) a simple kinematic model that possibly explains why large-eddy si

Filtering the Wall as a Solution to the Wall-Modeling Problem,in an LES, in which resolution is finite, it is inconsistent to locate the wall with precision. Instead we propose filtering through the wall using homogeneous or nearly homogeneous filters, effectively smearing it. The resulting filtered equations then have an explicit wall term, which is modeled u

Numerical Determination of the Scaling Exponent of the Modeled Subgrid Stresses for Eddy Viscosity modeling error in a LES using an approach based on Richardson extrapolation, where it is assumed that the modeling error scales like a power law. In order to apply this approach, the scaling exponent for the numerical error with respect to the filter width has to be known in advance. This scaling la

, Study on Modelling and Numerical Error in LES Applying the Smagorinsky Model,died and compared a posteriori in a turbulent plane Poiseuille flow. The gridindependent solution of the LES equations is approached keeping the product of the model coefficient and the length scale constant as the grid is refined. The aim is to clarify the choice of the model parameters via the two

Passive Scalar and Dissipation Simulations with the Linear Eddy Model,he modelling of turbulent combustion. In this context, emphasis was placed on the evolution of the scalar dissipation and its conditional moments. To allow for a systematic and quantitative analysis on the sensitivity of model to its input parameters, LEM has been employed as a stand alone model wit
