Research project: Investigations of Nonlinear Fluid-Solid Interaction Dynamic Systems for Wave Energy Harvesting

Currently Active: 
Yes

Increasing energy demands motivate the interest in energy harvesting concepts. In this work, we investigate, model and simulate nonlinear fluid-solid interaction dynamic systems to harness maximum wave energies based on its nonlinear characteristics.

Increasing energy demands motivate the interest in energy harvesting concepts, where the idea is to generate electrical energy for low power consumption devices in the local environment. Converting the kinetic energy associated with geophysical flows such as winds, rivers, and sea waves is particularly attractive, given the wide availability of this resource.

Increasing energy demands motivate the interest in energy harvesting concepts, where the idea is to generate electrical energy for low power consumption devices in the local environment. Converting the kinetic energy associated with geophysical flows such as winds, rivers, and sea waves (right-hand figure) is particularly attractive, given the wide availability of this resource.

The aim of this project is to investigate, model and simulate nonlinear fluid-solid interaction dynamic systems to harness maximum wave energies based on its nonlinear characteristics. Investigations by using a linear wave theory and the Laplace electromagnetic theorem for governing the interaction of electric converter-nonlinear oscillator-water waves, and numerical analysis have demonstrated the feasibility and the interesting potential of this system to harness wave energies.

Various extensions of this research (using different nonlinear oscillators, structures with elastic bodies, nonlinear wave theory, etc.) will be investigated by using mathematical modelling and numerical analysis with possible experimental validations or power generation. The expected outcome of this research will be a development of an effective mathematical model with a computer code, as well as a novel approach for nonlinear wave energy harvesting device designs to extract maximum power.
