- It goes in as a spray. Rocket engines normally make no attempt to vaporize
- the fuels on the way in; liquids are easier to handle and make better
- coolants. Localized small-scale boiling is sometimes permitted in cooling
- jackets, but without affecting the bulk of the coolant flow. There are
- some borderline cases like liquid hydrogen, which is often above its
- critical point (where the distinction between gas and liquid vanishes)
- in rocket applications.

- Designing a good injector gives lots of rocket engineers headaches. :-)
