Deep Underground Science and Engineering, EarlyView.Fluid flow through a single fracture is commonly described by the cubic law. However, deviations from this model are expected because natural fracture surfaces are rough and in contact with each other in discrete regions. In this study, the interactions between fracture closure, contact area, and hydraulic characterization of mesoscopic‐scale rough ...

Infrared Thermography and CFD Analysis of Hydrocarbon Jet Fires
Chemical Engineering Transactions, 2014 Fire modelling requires integrating the behaviour of hydrodynamics, heat and mass transfer as well as the combustion reaction. In the present paper, Jet Fires have been studied through CFD analysis, using the Reynolds-Averaged Navier-Stokes (RANS ...

Численное моделирование течения вязкого газа через плоскую решетку колеблющихся профилей [PDF]
, 2003 The numerical scheme of solving Reynolds-averaged Navier-Stokes equations for simulation of self -exciting oscillations of turbine blade row in transonic viscous gas flow is proposed. The method is based on second order Godunov's scheme.

Highly turbulent solutions of LANS-alpha and their LES potential [PDF]
, 2007 We compute solutions of the Lagrangian-Averaged Navier-Stokes alpha-model (LANS) for significantly higher Reynolds numbers (up to Re 8300) than have previously been accomplished. This allows sufficient separation of scales to observe a Navier-Stokes (NS)

Energy Science &Engineering, EarlyView.Passing vehicles generate short‐duration wakes that can be redirected toward a vertical‐axis turbine. The interaction between wake structure, blade count, and rotational speed governs transient torque production. Low‐solidity configurations combined with tuned rotational speed enhance energy extraction under vehicle‐induced gusts.

Predicting wind turbine blade loads using vorticity transport and RANS methodologies [PDF]
, 2009 Two computational methods, one based on the solution of the vorticity transport equation, and a second based on the solution of the Reynolds-Averaged Navier-Stokes equations, have been used to simulate the aerodynamic performance of a horizontal axis ...

Energy Science &Engineering, EarlyView.The Radial Force (RF) distribution under different cutting angles is presented in Figure 1. Generally, the distribution of RF displays divergence across different flow conditions. The pattern of force distribution reveals a total of 24 peaks, which corresponds to the number of blades of the impeller of the SCP.

Partially-Averaged Navier Stokes Model for Turbulence: Implementation and Validation [PDF]
, 2005 Partially-averaged Navier Stokes (PANS) is a suite of turbulence closure models of various modeled-to-resolved scale ratios ranging from Reynolds-averaged Navier Stokes (RANS) to Navier-Stokes (direct numerical simulations).
