Predvoditelev’s major works were on molecular physics, hydrodynamics, and thermal physics. He studied the processes of combustion, the distribution of waves in liquid and gaseous mediums, and the physical properties of liquids. He was engaged in the development of the theory of heterogeneous combustion. Predvoditelev collaborated on carbon combustion research and presented the findings in 1949 in his monograph The Combustion of Carbon (State Prize of the USSR, 1950). He also proposed methods for calculating the constants of working substances.
