    Biography

    Dr. Andrei Ermakov earned his PhD in 2020 from the University of Southern Queensland, Australia, with a focus on the Development of Rigorous Methods in Fluid Mechanics and Theory of Water Waves. He also holds a Candidate of Science degree (2011) and a Master's degree (2009) in Mechanical Engineering from Saint Petersburg State University, as well as a Bachelor's degree (2007) in Marine Engineering & Applied Mathematics from Saint Petersburg State Marine Technical University, Russian Federation.
     
    In January 2020, Andrei joined the Centre for Ocean Energy Research (COER) at NUI Maynooth as a postdoctoral researcher, contributing to the LiftWEC project supported by Horizon 2020, the EU's research and innovation funding programme. The LiftWEC project focuses on the development of a novel type of wave energy converters (WECs) that harness ocean wave energy using rotating hydrofoils in a Cyclorotor (horizontal cycloidal rotor).
     
    Following the successful completion of the LiftWEC project in 2023, Andrei secured independent funding to further advance cyclorotor WECs. His new initiative, "MaxRotorWEC," is partially funded by a research grant from Science Foundation Ireland and the Sustainable Energy Authority of Ireland under the SFI-IRC Pathway Programme. Additionally, he serves as an external lecturer in the Department of Electronic Engineering at Maynooth University.

    Maximising the power capture from cyclorotor wave energy converters (MaxRotorWEC) PI Ireland has one of the largest resources of ocean wave energy on the planet; however, the optimal method for the conversion of wave energy into electrical power has yet to be identified. The aim of the MaxRotorWEC project is to provide technical and economic solutions to the existing problems faced in the design of a radically new wave energy converter (WEC) concept that exploits hydrodynamic lift forces and can bring wave energy to commercial fruition. The proposed research is dedicated to the control design for a new and innovative type of wave energy converter which extracts ocean wave energy using a horizontal cyclorotor. The most recent experimental and numerical simulations have shown that this innovative type of WEC can be 40% more efficient than more traditional WECs, however the optimal design and real time control method for cyclorotor-type WECs still needs to be derived. The project will support the development of the control methods for the proposed new technology, focusing on demonstrating its commercial viability and strengthening Irish leadership in wave energy. This requires financial assessment, mathematical modelling and engineering optimisation of the concept in order to minimise the levelised cost of produced electrical energy (LCoE). A linearised mathematical model for the cyclorotor, new estimators and predictors for relative foil-fluid velocity will be developed. Cyclorotor-based WEC farms near the Irish coast will be modelled and performance assessed. The solution of the cyclorotor control problems will be beneficial for vertical H-Dareus wind turbines, tidal turbines, cyclocopters, and Voith Schneider type propellers. 01/12/2023 30/11/2027 535699
