Heat Transfer International Research Institute (HTI) was founded in 2005 and is based on more than ten years collaboration of «Laboratory of Heat Transfer Enhancement» of the Institute of Thermophysics Siberian Branch of Russian Academy of Sciences (IT SB RAS) and Microgravity Research Center (MRC) of Universite Libre de Bruxelles (ULB). Co-Directors of HTI are Professor Oleg A. Kabov (IT SB RAS) and Professor Jean-Claude Legros (MRC ULB).

The establishment of HTI has the intention to strengthen collaboration of researchers and to get remarkable progress in the field of sciences and technology of heat transfer in two-phase systems for ground and space applications. The main fields of research are:

  1. Two-phase flows in micro- and mini- channels with micro- and nano- coatings.
  2. Heat transfer, dynamics and crisis phenomena in liquid films rivulet and drop flows.
  3. Boiling and condensation on micro and nano- structured surfaces and in mini and micro-channels.
  4. Physics of fluids in microgravity.
  5. Evaporative and Marangoni convection.
  6. Evaporation and contact line phenomena.

HTI is involved in the preparation of several experiments of the European Space Agency (ESA) on the International Space Station, experiments in microgravity conditions and experiments on centrifuge. 9 campaigns of parabolic flights (more than 800 parabolas) have been already performed to research physics of fluids in microgravity and hypergravity conditions. The works conducted at HTI have the following areas of applications:

  1. Enhanced heat exchangers, condensers and gas-liquid separators for ground and space applications including Heat Pipes, Loop Heat Pipes and Capillary Pumped Loops;
  2. Advanced liquid cooling techniques with thin films moving under various driving forces (gravity, shear-stress, surface tension);
  3. Enhanced thin-film evaporators for better quality foodstuff (sugar, concentrated milk, fruit juices);
  4. Heat transfer devices and heat exchangers with micro and mini-channels.

HTI includes scientists of «Laboratory of Heat Transfer Enhancement» of IT SB RAS and some researchers of MRC. HTI also integrates partners - Honorary Fellows of other institutions from Canada, China, Europe, Japan, Russia, USA ... Participation of Honorary Fellows and intensive international cooperation is the backbone of HTI. The cooperation is based on joined research and projects development, on the joined exploitation of research equipment, on joined training of MS students, doctoral students and post-doctoral fellows, on participation in international collaborations, and on organization of seminars, workshops and international conferences. Since 2006 HTI is the main organizer of the yearly international Workshop «Two-Phase Systems for Ground and Space Applications». Sixth Workshop in 2011 is dedicated to the 50th anniversary of the first space flight of the Russian cosmonaut Yuri Gagarin on 12th April 1961.
