A Survey of Stratification in a Cryogenic Liquid
The fuel load in today’s missiles usually consists of at least one cryogenic liquid. In a missile second stage this cryogenic liquid is heated significantly by aerodynamic friction. To get maximum use from a propellant load, it is desirable to determine the effect of aerodynamic heating on the pool of cryogenic liquid. Since the net positive suction head (NPSH) is that portion of the total head above saturation pressure, a rise in the saturation temperature of the liquid due to aerodynamic heating will decrease the NPSH. Thus, the problem is one of defining drain temperatures resulting from flight conditions to determine the NPSH available.
