Oscillating Water Column
Junior Year Energy and Power Project - Oklahoma State University
In the Energy and Power BAE course, our class was instructed to split into small groups and choose from a list of project ideas to reinforce the practical portion of the course. I, along with my teammates, chose to create an oscillating water column to show how the movement of waves contains energy that can be converted and used to power a turbine. We were given creative freedom to design the project in any way we saw fit. This allowed us to do research on other existing water columns and mostly learn what would work from trial and error. We learned about the role volume played on the process and had to amend our dimensions and materials several times before arriving at a final design. We decided to use a gallon bucket attached to a water bottle to cause a change in diameter and increase suction. At the top of the bucket was a small one-way turbine. We submerged the system underwater and as we pulled the bucket up, the force would spin the turbine. We monitored the actual energy by attaching a digital multimeter to the turbine to determine the change in voltage with the movement. We used the formulas and calculations we were taught in class to determine how efficient our design was and how well the overall result worked. The presentation we showcased is included below.
