Experimental Heat Transfer and Pressure Drop of Film Boiling Liquid Hydrogen Flowing Through a Heated Tube
Liquid hydrogen appears to be a very attractive propeilant either in chemical systems in which it is burned with an oxidant, or as monopropellant when it is heated by some device like a nuclear reactor. Its low atomic weight, high specific heat and high heat of combustion all contribute to high specific-impulse values for either of the two propulsion systems. The undesirable characteristics of the propeilant include a large specific volume and difficult handling procedure for a low-temperature cryogen.
