The document discusses CFD simulations performed to analyze flow through an Invelox wind funnel from different directions. Key findings include: 1. Flow from the +x direction achieved a maximum velocity of 12.4 m/s and flow rate of 29.4 m^3/s through the funnel. 2. Rotating the funnel 45 degrees increased the maximum velocity to 13.9 m/s and flow rate to 36.4 m^3/s. 3. Flow from the +/-z direction had a maximum velocity of 10.2 m/s and flow rate of 23.49 m^3/s through the funnel.

INVELOX OPTIMIZATION Invelox Tower CFD Test - Flow From Different Directions Instructor : Professor Yiannis Andreopoulos Student : M.E. Mehmet Bariskan
HOW IT WORKS ? Capture, accelerate, concentrate. The name INVELOX comes from this dedication to INcreasing the VELOcity of wind. What the technology produces-energy is affordable, abundant, safe, and clean. INVELOX, by contrast, funnels wind energy to ground base generators. Wind is captured with a funnel and directed through a tapering passageway that naturally accelerates its flow. This stream of kinetic energy then drives a generator that is installed safely and economically at ground level. Bringing the airflow from top of the tower to ground level allows for greater power generation with much smaller turbine blades. It also allows for networking, allowing multiple towers to direct energy to the same generator.
