The Propagation of a Chain Isothermal Flame in a Random Medium
Autor: V. S. Posvyanskii, S. N. Medvedev, V. I. Oseledets
Publikováno v: Journal of Experimental and Theoretical Physics. 132:446-452
The dependences of the turbulent flame velocity in a random flow on the turbulence intensity have been studied in terms of the Kolmogorov–Petrovsky–Piskunov nonlinearity model in the one-dimensional case. We show that for a static random medium t

In this paper, we propose a method of three-dimensional direct numerical simulation of turbulent flame propagation in gas-reacting mixtures under stationary, homogeneous, and isotropic turbulence conditions. This method is based on the detailed kinet

Autor: Sergey Frolov, N. M. Kuznetsov, S. N. Medvedev, F. S. Frolov, Branislav Basara, K. Pachler
Publikováno v: NONEQUILIBRIUM PROCESSES: RECENT ACCOMPLISHMENTS.
The real-gas analytical equation of state (EoS) for nitrogen is developed. The applicability domain of the EoS is verified in a wide range of density (from 0 to the value at the triple point, 0.867 g/cm3) and temperature (from 100 to 5000 K). The obt

Low-Temperature Flameless Combustion of a Large Drop of n-Dodecane under Microgravity Conditions
Autor: S. N. Medvedev, V. Ya. Basevich, F. S. Frolov, S. M. Frolov
Publikováno v: Russian Journal of Physical Chemistry B. 12:245-257
The forced ignition, combustion, and spontaneous ignition of a drop of n-dodecane in an atmosphere of air at a normal pressure under microgravity conditions were studied based on a physicomathematical model of drop combustion and a detailed kinetic m

Rocket Engine with Continuous Detonation Combustion of the Natural Gas–Oxygen Propellant System
Autor: Igor O. Shamshin, N. N. Yakovlev, V.S. Ivanov, V. S. Aksenov, S. M. Frolov, S. N. Medvedev, I. I. Kostenko
Publikováno v: Doklady Physical Chemistry. 478:31-34
In a demonstrator of a detonation rocket engine (DRE) using the natural gas–oxygen propellant system, a high (270 s) specific impulse at sea level at a low (32 atm) mean combustor pressure was experimentally obtained for the first time. Comparison
