Analysis of a Stator-Rotor-Stator Spinning Disk Reactor in Single-Phase and Two-Phase Boiling Conditions Using a Thermo-Fluid Flow Network and CFD

Fluids, 2022
Cryogenic liquid propellants are used in liquid rocket engines to obtain high specific impulse. The flow rates are controlled by turbopumps that deliver liquid propellant to the engine at high pressure levels.

Interstellar travels aboard radiation-powered rockets [PDF]

Phys. Rev. D 99, 104081 (2019), 2019
We model accelerated trips at high-velocity aboard light sails (beam-powered propulsion in general) and radiation rockets (thrust by anisotropic emission of radiation) in terms of Kinnersley's solution of general relativity and its associated geodesics.

Radiation conditions in relativistic interstellar flight [PDF]

Acta Futura 2020, issue 12, 2020
Radiation hazard on board of a relativistic rocket can be of internal and external origin. Because of its highest specific energy density, antimatter is considered to be the preferred rocket fuel for accelerating a multi-ton rocket up to relativistic speed.

Regenerative Cooling Comparison of LOX/LCH₄ and LOX/LC₃H₈ Rocket Engines Using the One-Dimensional Regenerative Cooling Modelling Tool ODREC

Applied Sciences, 2023
Due to the extreme temperatures inside the combustion chambers of liquid propellant rocket engines, the walls of the combustion chamber and the nozzle are cooled by either the fuel or the oxidizer in what is known as regenerative cooling.
