Ground effect for ducted wind turbines: A computational study

Abstract Ducted wind turbines (DWTs) can take the advantage of ground effect (GE) when installed close to urban areas. To this aim, a parametric study investigate aerodynamic performance DWTs in relation three different distances are investigated. The flow around commercial DWT model using simplified duct actuator disc (AD) based on Reynolds Averaged Navier-Stokes (RANS) equations is performed. results indicate that placed will lead increased mass rate turbine plane, and thereby improving performance. However, additional force leads an asymmetric flow-field at which ultimately induce unsteady forces system. present analysis serve as strong recommendation address siting issues for manufacturers.
