    • Ultrasonic pulse generation by a piezoelectric transducer at cryogenic temperatures 

      Granados Jiménez, Marta (Universitat Politècnica de Catalunya, 2018-06)
      Bachelor thesis
      Open Access
      The use of cryogenic liquid propellants such as liquid hydrogen or liquid oxygen has arisen a problem for future space missions. As a result of long storage periods bubbles are formed in propellant tanks due to boil-off. ...
