Nominated by Tsinghua University as an outstanding thesis in the field
Proposes a raft-type wave-powered desalination device that can desalinate seawater directly
Conducts multiple-parameter analysis on power absorption and averaged permeate water flux using both analytical and numerical models
Develops mathematical models to evaluate the maximum mean power that could be captured by the raft-type device under motion constraints
Presents two power extraction enhancing strategies utilizing a spring-damping mass oscillator system and water tanks
This thesis proposes a new raft-type wave-powered desalination device that can convert wave power into hydraulic energy and use reverse osmosis (RO) to directly desalinate seawater. Both analytical and numerical methods are used to study the hydrodynamic characteristics of the device. Further, the thesis investigates the maximum power extraction and multiple parameter effects on power absorption and averaged permeate water flux. Lastly, it proposes and assesses two power extraction enhancing strategies. The thesis offers a valuable and important reference guide to ocean-wave-and-structure interaction and wave-powered seawater desalination for scientists and engineers alike.
