NONLINEAR DYNAMIC ANALYSIS OF WIND ACTIONS ON A CABLE-STAYED GLASS FAÇADE SYSTEM
International Journal for Computational Civil and Structural EngineeringThis paper presents the results of a nonlinear dynamic analysis of wind actions on a cable-stayed glass façade. The wind impact was determined by a transient eddy-resolving numerical simulation using a hybrid RANS-LES model SBES.

Engineering Applications of Computational Fluid Mechanics, 2018 The widely used improved delayed detached eddy simulation (IDDES) method is supposed to accurately predict the mean skin friction when it acts as wall-modeled large eddy simulation (WMLES), as claimed by the original authors.

FluidsThe Terra Incognita (or gray-zone) problem seen in atmospheric flow simulations causes serious consequences: it implies, e.g., significantly incorrect flow predictions and results that often simply depend on flow simulation settings as the computational ...

Assessment of Turbulence Models for Cylinder Flow Aeroacoustics
AerospaceNumerical simulations are performed for flows over a circular cylinder at a Reynolds number ranging from 150 to 5000, and Mach number of 0.2, to assess the predictive capability of URANS and hybrid RANS/LES for acoustic waves generation and propagation ...

Continuous Eddy Simulation vs. Resolution-Imposing Simulation Methods for Turbulent Flows
FluidsThe usual concept of simulation methods for turbulent flows is to impose a certain (partial) flow resolution. This concept becomes problematic away from limit regimes of no or an almost complete flow resolution: discrepancies between the imposed and ...

Model-Invariant Hybrid LES-RANS Computation of Separated Flow Past Periodic Hills [PDF]
The requirement that physical quantities not vary with a hybrid LESRANS model's blending parameter imposes conditions on the computation that lead to better results across LES-RANS transitions.

An algebraic model for prediction of bypass and separation-induced transition in turbomachinery boundary layers [PDF]
, 2016 An algebraic intermittency model for bypass and separation-induced transition is presented. The model modifies the production terms of a k-omega turbulence model. It uses only local variables and is tuned for turbomachinery flows.

Effects of the Fuel Species on the Combustion Pressure in a Two Staged Fueled Scramjet Combustor
AerospaceTwo-staged fuel injection configuration for scramjet combustors has been shown to be effective in distributing heat release in the combustor for preventing the unstart transition of the engine by suppressing peak pressure while increasing the pressure ...
