Numerical Simulation of Cryogenic Injection in Rocket Engine Combustion Chambers

Numerical simulation of combustion stability of liquid rocket engine based on chemistry dynamics

Combustion instability of O2/kerosene, O2/kerosene/hydrogen, and O2/kerosene/hydrogen spray flame is numerically studied. The numerical results of combustion self-oscillation are consistent with the historical experiments. Hydrogen is helpful to stabilizing oxygen/hydrocarbon combustion. High gas injecting velocity of the coaxial injector would increase the combustion stability. Contrary to the...

Numerical Simulation of Cryogenic Injection in Rocket Engine Combustion Chambers

The numerical simulation of cryogenic combustion is crucial for a better understanding of the complex physics involved in reactive flows of rocket engines and to help to reduce the development cost of these engines. The focus of this study is set on the oxidizer injection and its dispersion through jet dense core destabilization and atomization or supercritical mixing. Specific models have been...

a study of baudrillards ideas in brian moores fiction

پیدایش مرحله ی جدیدی از نظام سرمایه داری بعد از جنگ جهانی دوم همزمان است با ظهور عصر اطلاعات و رسانه جمعی. در چنین جامعه ای سیر آزادانه ی نشانه ها در فضای بی اساس مجازی بر سرعت فرسایش واقعیت می افزاید. به اعتقاد بودریار، فقدان واقعیت به واسطه ی شبیه سازی آن و تولید حاد واقعیت (hyperreality) پنهان خواهد ماند. این پژوهش بر آن است که جامعه فرانوین توصیف شده در سه رمان بریان مور را با توجه به نظر...
