What does it take to make history?  Be in the right place at the right time.  Namely, to be at the laboratory of heat pipes of the Department of Nuclear Power Stations and Engineering Thermal Physics (NPSETF). The lab developed heat pipes for the heat dissipation system of the landing module MASCOT (Mobile Asteroid Surface Scout), which last year delivered soil to the Earth asteroid Ryugu.

The winner of the University competition “Young Teacher-Researcher 2019” Yevhenii Serhiyovych Alekseik began his research career as a student in 2006. He then joined a research group of heat pipes supervised by Professor Volodymyr Kravets.  Based on research conducted as part of the group, Yevhenii wrote and submitted his Bachelor's and Master's theses and Candidate dissertation.

Now he is an Assistant at the Department of NPSETF. Since 2015 he has been teaching and doing research.  Yevhenii Alekseik teaches “Methods of research of heat exchange processes” (practical and laboratory classes, course design).  The main scientific interests of Yevhenii Alekseik are research on thermohydraulic processes in pulsation, miniature heat pipes and steam chambers, creation of cooling systems for electronic and space equipment based on two-phase heat transfer devices.  The teacher actively involves students of the department in scientific research.  Currently, Yevhenii is a co-executor of the state budget, economic contract, and international scientific projects.

Among the latter is the MASCOT space project. 

After covering more than three billion kilometers, the MASCOT landing module, descending from a height of 51 meters, took a series of photos. It also successfully landed on an asteroid and took the ground for research.     Engineers from the German Aerospace Center and the National Centre for Space Studies (CNES) of France developed the Mobile Asteroid Surface Scout. 

Initially, German scientists commissioned the design and manufacture of heat pipes for the thermal stabilization system at two institutes in Belgium and Spain.  They had worked for a year, but in the end, did not cope with the task.  Experts of Igor Sikorsky Kyiv Polytechnic Institute took to help European colleagues to create highly efficient heat transfer devices for the module.  The spacecraft needed heat pipes of a specific size, configuration, weight, and variable thermal resistance.  The Department of Nuclear Power Stations and Engineering Thermal Physics developed the project, while Yevhenii Alekseik was one of the developers.

The desired results did not come all at once.  It was necessary to divert the heat flow by about 30 watts.  For some time, the scientists received only 5 watts.  Then, they decided to create a capillary-porous structure based on pieces of thin copper wire.  The experiments have lasted for three months, and adjusting to the set parameters - two more. 

In total, the scientists have manufactured several dozen pipes until they could provide the optimal thermal modes of operation of electronic components. It did make a significant contribution to the successful implementation of this mission.

Today, the scientist is engaged in international projects. He is working on new two-phase heat transfer devices for cooling electronic components for Huawei.  Yevhenii Alekseik is the author of 36 scientific publications (three of them are part of the international scientometric database Scopus) and four patents.

Shortly, the scientist is planning to study two-phase heat transfer devices and develop new designs of such devices. He also wants to create effective heat transfer systems for electronic equipment and energy saving based on two-phase heat transfer devices.
