Harnessing of Wave Power from Horizontal Flow Dynamics of Shallow Waves

Abstract

Harnessing Ocean Wave power is a potential source of renewable form of energy. Our project was aimed at finding the constraints and proposing a suitable solution to utilize this form of energy. Ocean Wave Power is the most predictable, periodic and concentrated source among all renewable sources, but the constraints imposed on its harnessing are a result of its Ocean environment. Ocean wave dissipates energy in several strata of circular oscillation. But with depth induced water pressure these circular oscillation are squished into ellipse that approximates to back & forth motion. Statistically the horizontal oscillation shares the 68% of energy spectrum of wave energy. But due to irregular flow and variable pressure conventional hydropower harnessing techniques become improbable. In our project we have proposed a simple solution that takes the direct advantage of utilizing this energetic horizontal momentum of ocean waves, without in between conversion. In our project we have delved into finding the relevant parameters that govern the functioning of our device. Through the Spectral Analysis of Ocean Waves we have estimated the rate of input power and optimized the dimensions of our device to maximize its output. Finally we have tried to chart its efficiency along conventional lines. Our project has worked to realize a novel idea and model it on relevant information.
