Data-driven optimization of building-integrated ducted openings for wind energy harvesting: Sensitivity analysis of metamodels

Metamodels are developed and used for aerodynamic optimization of a ducted opening integrated into a high-rise building to maximize the amplification factor within the duct. The duct consists of a nozzle, a throat, and a diffuser. 211 high-resolution 3D RANS CFD simulations are performed to generate training and testing datasets. The space...

Computational analysis of ducted wind turbines noise

As the suitable locations for large wind farms in the mainland are limited, wind energy generation in the urban environment is gaining interest. The Diffuser Augmented Wind Turbine (DAWT) is a promising concept where the turbine is embedded into an airfoil-shaped diffuser (also named shroud or duct), which has the function of increasing the mass...

Computational Study Of Diffuser Augmented Wind Turbine Using Actuator Disc Force Method

In this paper, a computational approach, based on the solution of Reynolds-averaged-Navier–Stokes (RANS) equations, to describe the flow within and around a diffuser augmented wind turbine (DAWT) is reported. In order to reduce the computational cost, the turbine is modeled as an actuator disc (AD) that imposes a resistance to the passage of the...
