Oleg Glebovich Penyazkov (b. 03.01.1961, Minsk), thermal physicist. Academician of the National Academy of Sciences of Belarus (2014, corresponding member since 2009), Doctor of Physico-Mathematical Sciences (2004).

Scientific works in the field of high-temperature thermal physics, gas dynamics, physics of combustion and explosion. Received fundamentally new results on the evolution of the structure of detonation waves in gases, formulated criteria for the limits of detonation and deflagration in pipes. Established the modes and mechanisms of propagation of rapid combustion in heterogeneous systems, modes and critical conditions for the ignition of gases in collisions of shock waves. Determined the kinetic characteristics of high-temperature oxidation and decomposition of gaseous and liquid fuels. Developed original methods for diagnosing high-speed processes, including in turbulent flows and low-temperature plasma. The research results are of great importance for the development of theoretical ideas about non-equilibrium processes in chemically reacting heterogeneous flows, solving practical problems of creating direct-flow supersonic, detonation engines, internal combustion engines, burners, in the field of fire and explosive safety.

Penyazkov O.G. is a member of the International Institute of Combustion, the International Institute of Shock Waves, the International Center of Heat and Mass Transfer, the Board of Directors of the International Institute of the Dynamics of Explosions and Responsive Systems.

Author of more than 270 scientific papers, including 6 monographs (including chapters in collective monographs), 8 patents.
