    Влияние метеорологических параметров на оптимизацию процесса горения
    (Научные известия на НТСМ, 2015) Запорожец, Артур Александрович; Бабак, Виталий Павлович; Редько, Александр Александрович
    Considered the influence of meteorological parameters (temperature, pressure, humidity) on oxygen quantitative content in the air. Showed the bias that introduced with not accounting the parameter of the oxygen current concentration in the air during the energy calculations in the power system. On the basis of experimental data established the dependence of oxygen volume concentration in the air from meteorological parameters (temperature, pressure, humidity). Analyzed the seasonal changes of oxygen concentration in the air in 12 European capitals (based on 2014 year): Brussels (Belgium), Paris (France), Berlin (Germany), Vienna (Austria), London (United Kingdom), Helsinki (Finland), Warsaw (Poland), Bucharest (Romania), Prague (Czech Republic), Sofia (Bulgaria), Riga (Latvia), Rome (Italy). Proposed the method for eliminating the methodical error of the excess air ratio measurement based on current oxygen volume concentration in the environment.

    Экспериментальные исследования изменения объемной концентрации кислорода в воздухе и его влияние на процесс горения
    (Научные известия на НТСМ, 2016-06) Запорожец, Артур Александрович; Бабак, Виталий Павлович; Редько, Александр Александрович
    The effect of changes the volume oxygen concentration in the air on the combustion process are showed. Suggested the model for calculating the current concentration of oxygen in air depending from the main meteorological parameters – temperature, absolute pressure and relative humidity. Performed the experimental studies of the daily/seasonal changes of volume oxygen concentration in the air on the basis of direct and indirect measurements. Performed a metrological evaluation of results, confirmed the adequacy of the proposal model. Proposed a formula for calculating the air excess ratio based on the current concentration of oxygen in the air.
