1 ME 417 Design of Alternative Energy Systems Ocean Energy Calculations Wave Energy Conversion Assuming that the energy of a wave is in its potential energy, we can write the wave power as f V z) g( W wave wave wave sw wave Δ ρ = where wave W : power of the wave ρ sw : density of the sea water g: acceleration due to gravity ( Δ z) wave : height of wave V wave : volume of wave f wave : frequency of wave Assuimng the wave is sinusoidal, and approximating the sine function as a triangle, we could write wave wave wave wave w t ) z ( 2 1 V Δ = where t wave : thickness of the wave w wave : width of the wave Oscillating Water Column We consider that we have an initial state of air in the chamber (state 1), a final state of the air in the chamber (state 2), the state of the air entering the turbine (state 3), and the turbine exit state (state 4). We assume that the following are specified in the problem P 1 , V 1 , T 1 , V 2 , and P 4 and the following properties of air are known
