Аналитическое Определение Истинной Удельной Изобарной Теплоёмкости Компонент Воздуха И Продуктов Сгорания С Учётом Влияния Температуры И Давления И Эффекта Термической Диссоциации

Abstract: Предложены функциональные зависимости для нахождения истиной удельной изобарной теплоёмкости ср основных компонент воздуха и продуктов сгорания углеводородных топлив (азота, кислорода, углекислого газа, водяного пара, аргона) как функции температуры и давления в широком диапазоне температур и давлений с учетом эффекта термической диссоциации на основе обработки экспериментальных данных, полученных другими авторами. Функции представляют собой сложные полиномиальные зависимости, тем не менее, удобные для практ… Show more

“…In [25], dependencies of c p of gases as a function of temperature and pressure taking into account the effect of thermal dissociation, obtained by approximating experimental data were proposed. These dependencies can be used to determine the enthalpy of combustion products in the combustion chamber of air-breathing engines in the form of h(Т, р, q f ).…”

“…The equations с ра =f(T, p) for the main components of air and combustion products for hydrocarbon fuels, which are united throughout the specified pressure and temperature range (nitrogen р=0.1…200 bar, Т=150…2,870 K; oxygen: р=1…200 bar, Т=210…2,870 K; argon: р=1…200 bar, Т=190…1,300 K; water vapor: р=0.1…200 bar, Т=700…2,600 K; carbon dioxide: р=1…200 bar, Т=390…2,600 K) are obtained in [29], based on the results of [25]. The specific heat capacity averaged both by pressure and temperature can be obtained by integrating с ра =f(T, p) by pressure.…”
