Stern wave flow phenomena are investigated in a full-scale Kriso container ship. The hull roughness effects studied with and without propulsion. Reynolds-averaged Navier–Stokes (RANS) detached eddy simulations (DES) utilized the ghost-fluid method (GFM). DES is carried out submodel where stationary RANS solution used as boundary condition. surface effect on stern significant due to increased la...

The forward expansion hole improves the film cooling effectiveness by reducing penetration of coolant jet into main flow compared to cylindrical holes. In addition, compound angles improve promoting lateral spreading on a wall. Evidently, combination angle and shaped further adiabatic effectiveness. with 15° expansion, 35° inclination angle, 0° 30° at 0.5 1.0 blowing ratios was numerically simu...

Aerodynamic performances may be optimised by the appropriate tuning of Active Flow Control (AFC) parameters. For first time, we couple Genetic Algorithms (GA) with an unsteady Reynolds-Averaged Navier-Stokes (RANS) solver using Spalart-Allmaras (SA) turbulence model to maximise lift and aerodynamic efficiency airfoil in stall conditions [1], then validate resulting set optimal Synthetic Jet Act...

Physics-informed neural networks (PINN) can be used to predict flow fields with a minimum of simulated or measured training data. As most technical flows are turbulent, PINNs based on the Reynolds-averaged Navier–Stokes (RANS) equations incorporating turbulence model needed. Several studies demonstrated capability solve Naver–Stokes for laminar flows. However, little work has been published con...

Abstract Wind turbine interaction in wind farms can lead to energy loss and increased loads, with the magnitude of these effects strongly depending on atmospheric conditions. One-dimensional Reynolds-averaged Navier-Stokes (RANS) models are able represent boundary layer (ABL) over a range model fidelity, be used for steady-state inflow profiles three-dimensional RANS simulations farms. In prese...
