Simulation methods of rocket fuel refrigerating with liquid nitrogen and intermediate heat carrier
Engineering Education # 03, March 2014
DOI: 10.7463/0314.0699941
Refrigerating of high-boiling rocket fuel is needed to reduce its density and to create cold reserve for equalization of fuel heating during preparing and launching operations. Liquid nitrogen is cheap and ecologically clean product, which can be easily used as a source of cold in rocket fuel preparing systems. Refrigerating systems with liquid nitrogen injection, intermediate heat carrier and heat exchanger are used in temperature preparing of high-boiling rocket fuel components with relatively high freezing point. The operation principle of such system is based on liquid nitrogen injection into heat carrier and refrigerating a rocket fuel component with recuperative heat exchanger. The paper considers simulation techniques and results of such a system performance.
Building a rational scheme of preparation of hydrocarbon fuels according to temperature and moisture content with use of liquid and gaseous nitrogen at launch and technical spaceport complexes
Engineering Education # 10, October 2012
DOI: 10.7463/1012.0486647
The authors present results of theoretical investigations of heat and mass transfer processes in devices applicable to perform cooling and dehydration of hydrocarbon fuel in the start and technical space center complex. According to the results of the research the authors built a rational scheme of hydrocarbon fuel preparation system with due regard to temperature and moisture content, using storage tanks and storage containers, barbotage machines for preparation of fuel according to moisture content and temperature with use of cold of liquid nitrogen and the cold produced by evaporation of liquid nitrogen of gas nitrogen in the contact heat exchanger. The authors outline advantages of the proposed system over the systems based on the use of vapor-compression refrigeration machines.
