TY - JOUR TI - IN MEMORIAM: Academician Vladimir E. Nakoryakov (July 26, 1935 - April 1, 2018) AU - Alekseenko Sergey V AU - Oka Simeon JN - Thermal Science PY - 2018 VL - 22 IS - 4 SP - 0 EP - 0 PT - Article AB - Vladimir NAKORYAKOV is an outstanding scientist in the field of thermophysics and physical hydrodynamics and an author of more than 600 scientific publications, including 12 monographs. He made a great contribution to the development of gas-liquid flow hydrodynamics, electro-diffusion method of two-phase flow diagnostics, wave dynamics of two-phase media, film flow, unsteady processes in multiphase systems, convective heat and mass trans-fer in porous media, combustion, and heat and mass transfer in the acoustic field. Vladimir Nakoryakov's works initiated the new research fields, which are now being actively developed in Russia and abroad. Under his supervision and direct participation, the existence of rarefaction shock waves in a homogeneous medium was discovered experimentally for the first time. He laid the foundations of absorption theory, which is used in heat pump engineering, and developed several research avenues in renewable energy and energy efficiency technologies.
