Analysis of SGS effects on dispersed particles in LES of heated channel flow along the particle trajectories is applied to account for subfilter flow effects on particles. It is shown that both the particle dynamics and temperature are affected by the model. Results for the carrier and dispersed phases are presented in terms of their velocity and thermal statistics. The need for further model improvement is discussed.

Error-landscape assessment of large-eddy simulations: a reviewe solution. Subsequently, the error-landscape method is further illustrated by comparing different numerical discretizations for Smagorinsky LES. Finally, a more complex case, i.e. a high (infinite) Reynolds number boundary layer, is considered.

Analysis of the subgrid models in the flow between rotating discss some parameters which influence the model behavior. We found that in this type of flow this procedure should be directly related to the numerical scheme applied. Otherwise the results depend on the initial flow conditions and the predicted evolution of turbulent flow may be distorted.

A priori analysis of an Isothermal, Turbulent Two-Phase Flowcal isotherm. After description of the numerical method, results of the Direct Numerical Simulation of a classic benchmark problem are shown. Next, . related to the nonlinear pressure and capillary terms are studied by means of an a priori analysis based on DNS results, and a subgrid model for these terms is proposed.
