— [8] proposed that the centerline maximum velocity and plume width were both functions of the fluidization rate. Increasing the fluidization velocity decreases the maximum centerline velocity and widens the velocity profiles for both phases as shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5.As expected, Fig. 2 shows that the centerline gas phase velocity for all …

 — Vertical-axis wind turbines (VAWTs) are receiving more and more attention as they involve simple design, cope better with turbulence, and are insensitive to wind direction, which has a huge impact on their cost since a yaw mechanism is not needed. However, VAWTs still suffer from low conversion efficiency. As a result, tremendous …

Turbulent Flow Velocity Profile: Examination and Features. In contrast to laminar flow, turbulent flow is chaotic, characterised by randomness, and highly sensitive to initial conditions. The turbulent flow velocity profile denotes the way fluid velocity varies across the flow field. Its unpredictable and complex nature makes it more ...

Wind energy is considered one of the most important sources of renewable energy in the world, because it contributes to reducing the negative effects on the environment. The most important types of wind turbines are horizontal and vertical axis wind turbines. This work presents the full details of design for vertical axis wind turbine (VAWT) and how to find …
