Background

Dr Könözsy received his first PhD degree in engineering sciences at the University of Miskolc, in Hungary (2004). Prior to his position at Cranfield University, he was a guest research fellow at the University of Siegen (2003) and at the Otto-von-Guericke-University Magdeburg (2005), in Germany. He was working on mathematical modelling and numerical method development of isothermal and non-isothermal turbulent flows by using a stochastical turbulence model. He held an Assistant Professor position at the University of Miskolc teaching for seven years in the Hungarian Higher Education system. He became a Post-Doctoral Research Fellow at the University of Leoben, in Austria, 2006. He took part in and led industrially sponsored research projects working on modelling of multiphase and multicomponent solidification and melting processes of ingot casting. His interest turned to the field of micro- and nanofluidic applications in particular to multiphysics modelling of complex fluid dynamics processes at small physical length scales.

Dr Könözsy decided to further educate himself for a second PhD degree at Cranfield University in the field of computational fluid dynamics (CFD) and multiphysics modelling.

Currently, he is working on and developing different numerical methods for complex physical problems with strong collaboration with industry both national and international levels.

Current activities

Dr László Könözsy is a Senior Lecturer in Fluid Mechanics and Computational Engineering in the Centre for Computational Engineering Sciences at Cranfield University. He is the Course Director of the MSc in Aerospace Computational Engineering. He has a broad range of experience in different fields of fluid mechanics, computational sciences, heat transfer and computer programming for solving complex academic and industrial problems. He is the author of two books on anisotropic turbulence modelling published by Springer. These two books together received 72000+ views on LinkedIn and these books are the only ones on the current book market worldwide which are solely focusing on a novel anisotropic engineering turbulence modelling approach.

Dr Könözsy is the author of two Springer books, an author/co-author of 100+ scientific work including six book chapters in different books, 40+ peer-reviewed journal publications, 50+ conference papers, and 15+ scientific research reports. He supervised 10+ PhD research students and 170+ postgraduate MSc students at different universities. He established the MSc in Aerospace Computational Engineering course at Cranfield University which is among the top 5 computational method-based MSc courses in the field of aerospace engineering in the United Kingdom. He was awarded "The Best Lecturer" and "The Best Research Supervisor" prizes for his teaching and supervisory excellence at the School of Aerospace, Transport and Manufacturing in the Academic Years 2014/2015 and 2015/2016, respectively. He won these Student Led Teaching Awards (SLTA) from the Cranfield Students' Association (CSA) based on the nominations and votes of MSc and PhD postgraduate students at Cranfield University. He was awarded 9 times for supervisory excellence and he taught 2500+ hours over his academic career.

Dr Könözsy has educational and research award-winning PhD and MSc students who have worked under his primary supervision in different research projects. One of my former MSc and PhD students won the Lord Kings Norton Medal in 2019 which medal is the prize awarded only for the best performing doctorate student at Cranfield University, in the United Kingdom. One of my former MSc students was the winner of the Vice-Chancellor's prize in 2020 which is awarded annually to the most outstanding taught course student at Cranfield and he received the Course Director's prize for the best overall achievement on the MSc in Aerospace Computational Engineering course. Another MSc student who worked under my supervision won the Course Director's prize for "The Best MSc Thesis" in 2019 on the MSc in Computational Fluid Dynamics (MSc in CFD) course at Cranfield.

Research areas of Dr Könözsy are as follows:

Development and implementation of an acoustic streaming model for acoustic liquid manipulation (ALM) in microgravity environment for space applications.
Improvement of a three-dimensional anisotropic stochastical turbulence model in particular to external flows for automotive/motorsport industrial applications.
