Design and comparative analysis of an INVELOX wind power generation system for multiple wind turbines through computational fluid dynamics

Abstract

Increase velocity in omnidirectional (INVELOX) is the wind power transporting system, which is suitable for providing the maximum wind energy for better maneuver of wind turbine. This venturi has innovative features that are accomplished for functioning the integrating multiple wind turbine generator system, capture the wind flow through the omnidirectional intake and speed-ups the flow across the venturi region that is release into ambient environment through diffuser. In this study, INVELOX model 1 and model 2 are designed for investigation of pressure and velocity contours. Power output of turbine depends on pressure and velocity of wind. The venturi section result specifies velocity and pressure drop of both models of INVELOX; velocity of model 1 and model 2 increases from 10.42 to 45.5 m/s, respectively. Pressure drops transpire in model 1 and model 2 which decrease from − 1 . 722 × 10 1 and − 6 . 938 × 10 2 Pa , respectively. Upstream velocities and power of wind after throat of venturi are deliberated. The second and third turbines provide the less potential as compare to first turbine power. It is concluded that the power produced using multistage wind turbine is higher.
