Research interests

My main research interests lie within the energy related topics as reactive and multiphase flows and fundamentals of phase change processes at normal and trans/super-critical conditions, and under wide-span time scales, from mili-to-micro/nano-seconds.


These find relevance in fields such as energy sustainability, propulsion, micro-fluids, safety and energy management. Those topics are of emerging importance in the environmental energy field due to fossil sources depletion and due to the ongoing miniaturization process of devices.

The energy and environmental field encounters inter-disciplinary challenges at every corner. One of the most intriguing fuel that I am researching is methane-hydrate, which is the most common of a wider family of gas-hydrates, found on the continental shelves and in the permafrost.

Short Bio

Tali Bar-Kohany received a Ph.D. in mechanical engineering at Ben-Gurion University (BGU, 2004). She won the WOLF award for outstanding Master achievements in 2000 and the Kazir scholarship by the ministry of defense in 2004, and since then she is employed at nrcn. In 2010 she received an honorary fellowship from the Australian institute of high energetic materials. During 2013-2014 she spent a Sabbatical at UCI, working with professor W.A. Sirignano on the subject of combustion of methane-hydrates, which will be the topic of her talk. During 2017-2018 she spent a Sabbatical at UMD, College-Park, working with professor Jungho Kim on fundamental aspects of liquid-vapor phase change.
