Abstract: As online educational experiences have become more common for students to engage with while earning an engineering degree, instructors must become more attuned to best practices in digital pedagogies for all courses, ...

Abstract: Neutron imaging enables direct visualization of evaporation and condensation of cryogenic propellants in metal containers such as aluminum and stainless steel. CFD models of propellant behaviors inside the large tanks have ...

Abstract: The condensation and evaporation of hydrogen under cryogenic conditions is visualized by using neutron imaging at the BT2 Beam Facility at the National Institute of Standards and Technology (NIST). The condensation and ...

Abstract: The control of propellant boiloff is essential in longterm space missions. However, a clear understanding of propellant cryogenic condensation/evaporation in microgravity is lacking. One of the key factors in designing ...

Abstract: One of the key limitations to longterm space missions is to avoid propellant boiloff in a microgravity space environment. Even with the use of active and passive controls of propellants, boil off is inevitable. Longterm ...
