Understanding, predicting, and controlling fluid slosh dynamics is critical to safety and improving performance of space missions when a significant percentage of the spacecraft’s mass is a liquid. Computational fluid dynamics (CFD) simulations can be used to predict the dynamics of slosh, but these programs require extensive validation. Many CFD programs have been validated by slosh experiments using various fluids in earth gravity, but prior to the ISS SPHERES-Slosh experiment, little experimental data for long-duration, zero-gravity slosh existed. This presentation provides a description of the design details of the SPHERES Slosh Experiment (SSE), aboard the International Space Station. The description spans various design elements including the mechanical, electrical and software design and create a background for developers creating their own payload. The SSE is designed to acquire long-duration liquid microgravity data used by engineers on earth to validate and improve the CFD prediction models, improving the design of the next generation of space vehicles as well as the safety of the current missions.
Hector Gutierrez received the Ph.D. degree in Electrical Engineering in 1997 and the the M.Eng. Degree in Manufacturing Systems Engineering in 1993, from North Carolina State University. He received the B.Sc. Degree in Applied Mathematics from Universidad Cayetano Heredia, Lima, in 1989, and the B.Sc. in Mechanical Engineering from the Pontificia Universidad Catolica del Peru in 1991. He has been with the Department of Mechanical & Aerospace Engineering, Florida Institute of Technology since 1999, where he is currently a Professor. His professional interests are in automatic control and mechatronics for aerospace systems, motion control, and flexible structures. He received the National Science Foundation CAREER Award in 2001 and the Office of Naval Research Young Investigator Award in 2003, both for his work in magnetic suspension systems.
