Документ Comparison of spark channel expansion in hydrogen, oxygen and nitrogen(Національний науковий центр "Харківський фізико-технічний інститут", 2020) Korytchenko, K. V.; Kashanskyi, Yu. V.; Cherkashyn, O. V.; Belyuchenko, D. Yu.; Maksimov, A. V.; Nikorchuk, A. I.; Chernenko, P. V.The results of the spark channel expansion simulation in various gases such as hydrogen, oxygen and nitrogen have been presented. Difference in thermodynamic properties of the various gases has been taken into account. Influence of a type of gas on the discharge current, the spark resistance, the energy deposited in the spark and the spark gas-dynamic expansion has been found out. Influence of initial species concentration in mixture of nitrogen, hydrogen and oxygen on detonation initiation by spark discharge has been discussed.Документ Modern substancesfor ir smoke screening(Національний технічний університет "Харківський політехнічний інститут", 2020) Linyvtsev, O.

V.Документ Numerical simulation of gap length influence on energy deposition in spark discharge(Національний технічний університет "Харківський політехнічний інститут", 2021) Korytchenko, K. V.; Shypul, O. V.; Samoilenko, D.; Varshamova, I. S.; Lisniak, А. A.; Harbuz, S. V.; Ostapov, K. M.The research is carried out by numerical modeling of the process of spark discharge development at variable values of the discharge gap length and at invariable other discharge conditions. The length of the gap was set in the range from 1 mm to 20 mm. The study was conducted using a numerical model of spark development, which takes into account the processes of nonstationary gas-dynamic expansion of the spark channel, the transient process in the electric circuit, nonequilibrium chemical processes, gas ionization, heat transfer and electrons thermal conductivity. The simulation was performed in atmospheric pressure nitrogen. The calculation was performed for various parameters of the RLC circuit, such as capacitance, inductance, resistance and voltage across the capacitor.Документ Requirements to the electrical discharge system used in the plasma-wave system(Національний науковий центр "Харківський фізико-технічний інститут", 2004) Korytchenko, K. V.; Dovbnya, A. N.; Volkolupov, Yu. Ya.; Tur, Yu. D.; Shkirida, S. M.; Yanchik, A. G.The electrical circuit creating a pulse arc is analyzed. The requirements to the elements of an electrical circuit in the electrical discharge circuit applied in the plasma-wave system are considered [1]. For analysis a discharge gap as a loading in the similar circuits is offered. The experience of practical realization of the circuit under consideration is given. Dynamics of an energy release in the channel of a pulse arc being characteristic for the chosen discharge circuit is experimentally established.
