Biography

Adi is a research fellow with Marine Energy Research Australia (MERA), The University of Western Australia (UWA). His research covers aspects of wave energy conversion, wave-structure interactions, and multi-objective optimisation. He has numerically modelled a variety of wave energy converters (WECs) and is deeply interested in how geometry and motion influence wave absorption and loads.

Adi obtained his PhD in Marine Technology from the Norwegian University of Science and Technology (NTNU). During his PhD, he participated in the NumWEC project: Numerical estimation of energy delivery from a selection of wave energy converters, a collaboration between NTNU and Centrale Nantes comparing the performance of several different WECs through numerical modelling.

Before joining UWA, Adi was with Aalborg University, Denmark, and the University of Plymouth, UK. His research into flexible deformable WECs, initiated while he was at Plymouth, was among the first of its kind. There is a continued interest in this idea, given the potential benefits of using flexible materials over rigid ones. While at Aalborg, he participated in the WEC modelling task force of the International Energy Agency - Ocean Energy Systems.

Since joining UWA, Adi has been involved in several research activities, including developments of efficient methods for deterministic prediction of ocean waves, multi-objective optimisation of arrays of WECs, simplified modelling of parametric resonances in WECs, modelling and optimisation of articulated WECs, developments of methods to detect false rogue waves, and comparison of WECs, which has been his long-standing interest. He is currently supervising a number of Master’s students on projects related to marine renewables. He is responsible for teaching parts of OCEN4007 Renewable Ocean Energy.

Adi is the co-author of Ocean Waves and Oscillating Systems: Linear Interactions Including Wave-Energy Extraction (2nd edition) with Professor Johannes Falnes (NTNU). Since 2020, Adi has been a member of the Standards Australia Committee EL-066 on Marine energy - Wave, tidal and other water current converters.

Projects

Comparison of wave energy converters
Although many fundamental results on wave power absorption were discovered in the 1970s and 80s, the most economic way of harnessing wave energy remains an open question. This ongoing project aims at developing new non-dimensional metrics to assess the relative cost-effectiveness of different wave energy converters.

Characterisation of wave energy resource in Albany, Western Australia
Compared to the Northern hemisphere, wave climates of the Southern hemisphere have higher consistency and lower seasonal variability. Low variability is advantageous because cost is correlated with extreme-to-mean ratios. This project seeks to characterise the wave energy resource of Albany, Western Australia, which has been identified as a promising location for wave energy utilisation.

Compressible wave energy converters
Compressible or variable-volume wave energy converters are a type of wave energy converters that expands and contracts under wave action. Owing to their unconventional modes of motion, such devices can have more superior properties than rigid devices.

Optimisation of arrays of wave energy converters
Most studies on optimisation of arrays of wave energy converters are concerned with maximising the overall power output as the sole objective. This project considers this problem from a multiobjective perspective. Instead of a single solution, multiple solutions are sought, providing an insight into which arrays are optimal for each of the competing objectives.

Fast deterministic wave-by-wave prediction of real ocean waves
It is well-known that the power production of a wave energy converter can be significantly increased if we can tune it to respond optimally to each incoming wave. This project aims to develop fast wave-by-wave prediction tools to accurately predict weakly nonlinear waves in unidirectional and multidirectional seas. Applications range from wave energy control to offshore operations and recreational activities.

Modelling and optimisation of the M4 wave energy converter
The M4 is a multi-float wave energy converter developed by Professor Peter Stansby from the University of Manchester. This project seeks to develop a numerical tool to optimise the design of the device. The tool couples a dynamic model of the device and a boundary element software.

Modelling and simulation of parametric resonance in wave energy converters using a simplified model
Parametric resonance is a nonlinear phenomenon in which an oscillating system responds at a frequency different from the excitation frequency. Some wave energy converters are prone to this phenomenon, which can degrade their performance. The aim of this project is to develop fast, simplified models to capture this nonlinear response in the time domain.
