Role

Iakovos Tzanakis is a Professor in Engineering Materials in the School of Engineering, Computing and Mathematics (ECM) at Oxford Brookes University. He is also a Visiting Fellow at the University of Oxford (Department of Materials) and Bournemouth University (Department of Design and Engineering).

Iakovos studied Mechanical Engineering in Greece (2005) followed with a Master of Science (MSc) in Energy Systems and the Environment from the University of Strathclyde (2007) and a PhD in Tribology and Design received from Bournemouth University in 2010.

He then worked as a Research Fellow in Bournemouth University (2010-2012) where he conducted research related to tribology and cavitation erosion of scroll expander systems in collaboration with Energetix Group (UK).

Iakovos then joined BCAST at Brunel University London as a Research Fellow for the UltraMelt project (2013-2016) funded by the Engineering and Physical Sciences Research Council (EPSRC). During this time he pioneered advanced characterisation of ultrasonic cavitation processing in liquid aluminium alloys. 

Subsequently, Iakovos was appointed as a Lecturer (2016) at Oxford Brookes University, gaining promotions to Senior Lecturer (2017), Reader (2018) and Professor in 2019.

Research

Iakovos main field of research is the fundamentals and applications of ultrasonic processing and cavitation bubble dynamics with major contributions to modern views on the mechanisms of ultrasonic cavitation melt processing.

He has established a multi-disciplinary ultrasonic processing research facility within ECM. Its core activities range from structural materials (aluminum), functional 2D nanomaterials (graphene) and composites (thermoplastic, metal-matrix) to engineering emulsions (oil/water systems, self-lubricating monotectic alloys) and cavitation resistance (steels, thermal coatings).

The focus of his work is primarily experimental, using in-situ imaging:

  • a Photron SAZ-2100K high-speed camera capable of 2.1 million frames per seconds,
  • Particle Image Velocimetry (TSI), 
  • and synchrotron X-ray radiography

His work also uses acoustic measurements employing a series of NPL-calibrated (in the range of 8 kHz ̶ 30 MHz) hydrophones and high temperature (up to 800 °C) cavitometer with sensors probe size ranging from 10 μm to 4 mm.

This advanced experimental configuration is used to monitor bubble activity and acoustic flows and resolve the acoustic spectrum of cavitation and shock wave emissions in various low and high temperature liquids. The configuration is also used to link cavitation behaviour to applications related to materials processing. 

Parallel activities include wind energy, tribological studies of biomimetic surfaces, ultrasonic atomization of metals and additive manufacturing. 

Iakovos is currently a Principal Investigator in one H2020-funded project and two EPSRC-funded projects. He has 60 papers (Scopus) published (H-index 21) with more than 1000 citations.

Recent projects include:

  • Upscaling environment-friendly cavitation melt treatment (UltraMelt2, EPSRC)
  • Sustainable and industrially scalable ultrasonic liquid phase exfoliation technologies for manufacturing 2D advanced functional materials (EcoUltra2D, EPSRC)
  • Biomimetic laser surface patterning for friction and wear reduction of automotive components (NFFA ̶ EUROPE)
     

Projects as Principal Investigator, or Lead Academic if project is lead by another Institution
