RISFlow Characterization of Bluff Bodies: A Two-Dimensional Transformation From Square to Triangular Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, two-dimensional unsteady, incompressible flow around a square body that is being transformed into a vertex oriented toward the flow configuration of a triangular body is numerically investigated at Re =100 ...
Hybrid/Combined Darrieus–Savonius Wind Turbines: Erstwhile Development and Future Prognosis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Over the last few decades, the vertical-axis wind turbines (VAWTs) have undergone intensive research mainly due to their design simplicity and independency of wind direction. The drag-based Savonius wind rotor exhibits a ...
Capturing the Dynamic Stall in H-Type Darrieus Wind Turbines Using Different URANS Turbulence Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The occurrence of dynamic stall phenomenon in an H-type Darrieus wind turbine with low tip speed ratio (TSR) has been numerically investigated on a single-bladed rotor with NACA 0012 airfoil. The Reynolds number (Re) ∼105 ...
