The Laboratory of Chemical Physics specializes in design-theoretical works in the field of thermal physics, chemical physics, combustion physics, physical kinetics, and hydrodynamics. The majority of works are dealing with solving urgent applied problems. Experimental works in the field of combustion and filtration combustion are being conducted. In 1989, the Laboratory of Chemical Physics was born from the Laboratory of Thermal Aerodynamics that was established and headed by Prof. B.M. Smolsky. Under B.M. Smolsky the staff of the Laboratory designed unique experimental setups – wind tunnel, optical test bench, etc. At the end of the 70s, the researchers of the Laboratory started investigating gas kinetic processes in gases, including vibrational, electronic relaxation of СО, N2, NO of other molecules. Since 1987, the Laboratory was headed by S.A. Zhdanok. The investigation of so-called superadiabatic combustion in porous media (filtration combustion) became a continuation of complex heat and mass transfer processes in multi-phase systems. This research line was developed in succeeding years. For the first time, physics of filtration combustion of gases and front stability problems were described progressively. In 2000, as a result of the restructuring of the Institute, the Department of Non-Equilibrium Processes was organized on the base of the Laboratory of Chemical Physics and the Laboratory formed a part of this Department. During the ensuing years the Laboratory of Chemical Physics was a part of the Department of Mathematical Modeling, and since the end of 2006 – the Department of Energy Physics headed by Academician O.G. Martynenko.
