About

Overview

Dr Ioannis Karathanassis received his PhD from the National Technical University of Athens in 2015 specializing in heat-transfer enhancement techniques and design of cooling devices. His PhD dissertation has been awarded as the best in applied sciences for the year 2015 by NCSR “Demokritos”, the largest research centre of Greece. In the time period 2009-2015, he was also a Research Associate of the Solar & other Energy Systems Laboratory of NCSR Demokritos, where he designed experiments for the evaluation of various renewable-energy applications. Since June 2015, he is working as a Marie Curie/Research Fellow at City, University of London where his research interests comprise modelling of cavitating and boiling flows in injector orifices, as well as experimental measurements and visualization of highly-transient cavitating flows. Dr Karathanassis has a deep understanding of flow-separation mechanisms and mass-transfer processes. From an experimental point of view, he is highly experienced in the development of experimental procedures suitable for the characterization of complex flows.

Research

Dr Karathanassis is currently working on compressible multiphase flows with phase-change and non-idealised fluid properties. More specifically, his research focuses on the study of cavitation formation and induced erosion in practical applications with reference to the automotive and energy industries, such as high-pressure fuel injection and auxiliary equipment, e.g. fuel pumps and hydraulic fittings. In terms of numerical modelling, he is familiar with several methodologies suitable for the prediction of phase change rate in two phase flows including detailed equilibrium, bubble dynamics and semi-empirical models, e.g. the Homogeneous Relaxation Model and formulations based on the kinetic theory of gases, extending to other phase-change regimes, apart from cavitation, such as flash boiling. The numerical models he has developed have been implemented in commercial CFD software, as well as in-house codes and have been passed on to industrial partners (Perkins Engines UK, Caterpillar Fuel Systems) for the prediction of cavitation in Diesel injectors and high-pressure piston pumps.

In reference to experimental activities, Dr Karathanassis's research activities include high-speed, shadowgraphy visualisation studies of in-nozzle cavitating flows for various types of mineral and additised Diesel fuels, as well as high-speed, X-ray phase-contrast and absorption imaging The main focus of his research is to quantify, in terms of vapour generation, and elucidate the topology and dynamics of the transient features of cavitating flow, which are possible to emerge and have a considerable impact on different hydrodynamic machines and other devices, such as ship propellers, turbomachinery blades, high-pressure pumps and fuel injectors. In the course of his appointment at City, he has collaborated closely with a large number of engineers and researchers from partners of various projects, including the Argonne National Laboratory, Caterpillar Fuel Systems (USA), Perkins Engines UK, Lubrizol Ltd. UK, the University of Bergamo (Italy) and TU Delft (Netherlands).

Besides, owing to his doctoral studies, Dr Karathanassis has significant experience in the implementation of novel techniques and the design of devices suitable for the cooling of high-flux heat sources. He has investigated various heat-transfer enhancement techniques, i.e. jet-impingement, linear vortex generators, stacked microchannels, serpentine tubes, dendritic configurations and metal foams. Furthermore, hes has formulated non-deterministic optimisation algorithms to dermine the optimal geometrical layout of heat-sink devices that have been designed, manufactured and their performance has been experimentally evaluated using purpose-specific test rigs developed.
