Experimental and simulated results indicated that the tank pressure decreases during the N2O self-pressurization process.
Self-pressurization analysis of the natural circulation integral nuclear reactor through a new dynamic model is studied.
Residual heat loads, due to heat conduction in the launcher structure or solar radiation, induce cryogenic propellant vaporization and tank self-pressurization.
In this paper, a two-phase CFD model is presented that describes the self-pressurization behavior of a flightweight partially full LH2 tank in normal gravity.
The IMR adopts natural circulation and self-pressurization in the primary cooling system, and a reactor vessel built-in steam generators.
The characteristics of the N2O self-pressurization feeding process as well as the preheating process of a sub-Newton N2O thruster were studied.
In order to obtain the dynamic characteristics of a differential piston warm gas self-pressurization system for liquid attitude and divert propulsion system, a transient model is developed using the modular modeling method.
Self-pressurization model is developed based on conservation of mass, volume, and energy by predicting the condensation that occurs in the steam dome and the flashing inside the chimney using the partial differential equation.
The Thermodynamic Vent System (TVS) permits to control self-pressurization using the following procedure: a fraction of liquid propellant is removed from the tank by a pump, cooled down by a heat exchanger and re-injected inside the tank as a jet or a spray.
In optimizing the design of cryogenic storage facilities for future in-orbit or on-surface applications the boil-off and the self-pressurization rates must be accurately predicted for different g-levels and for a variety of heat loads and distributions.
The gas also self-pressurizes, which could eliminate the need for tank-pressurization systems.
