Hosted the UNL Department of Mechanical & Materials Engineering, Jeffrey R. Didion and Mathew Showalter of NASA's Goddard Space Flight Center will speak at UNL on Tuesday, Sept. 25 at 4 p.m. in Jorgensen Hall, Room 110. Their topic is Development of Milli-, Micro- and Nano-scale Electrohydrodynamic (EHD) Based Thermal Control Subsytems at NASA-GSFC.
Electrohydrodynamic (EHD) Thermal Control Systems (TCS) operate by applying an electric field to a dielectric fluid that, in turn, generates a force that can be used to pump fluids and separate liquid and vapor phases in two-phase flow.
The EHD-TCS Technology Development at Goddard Space Flight Center in Greenbelt, Md. is a comprehensive program that investigates fundamental EHD phenomena, fabricates prototype hardware and validates the prototype systems for spaceflight mission infusion.
This talk will present an overview of the EHD phenomena and discuss the technology development program as well as its target spaceflight applications and the current spaceflight validation efforts including variable gravity and sounding rocket missions.
