Расчет и корректировка упругих свойств моторных топлив и других жидкостей

Обоснована необходимость конкретной формы уравнения состояния, отличающейся простыми и удобными для использования выражениями, которые позволяют быстро и с достаточной точностью определять упругие свойства моторных топлив. Предложен удобный метод расчета констант для выбранной формы уравнения состояния и представления их в виде выражений, отражающих зависимость констант от температуры топлива. На основании экспериментальных данных по выбранному параметру — скорости звука, приведенных в литературных источниках, предложен метод увеличения точности расчета путем введения в расчетные выражения универсальных коэффициентов, отражающих нелинейное влияние температуры и давления для каждой рассмотренной жидкости. Продемонстрирована возможность применения разработанных методов поиска констант уравнения состояния и увеличения точности расчетных данных для топлив, калибровочных и иных технических жидкостей.
