Abstract:

It is important to analyze the flow resistance of the tank，not only to provide the information to analyze the flow resistance of the whole propulsion system，but also to provide the standard for choosing the tank used in the parallel system．Through analyzing the flow resistance，the most important part contributing to the flow resistance of the tank can be found，which should be manufactured under more rigorous contr01．In the paper，the flow resistance of a large volume tank is analyzed．Firstly，the mathematic model of the flow resistance of the tank is established．Secondly，the model is used to analyze the flow resistance under a variety of operation conditions．Finally，the distribution of the flow resistance on the PMD of the tank under a variety of operation conditions is obtained，and the relation between the flow rate and the flow resistance is also obtained．
