Cryogenic Line Quench Experiment In Microgravity, Kanishkan Sathasivam

Masters Theses

This experiment was designed to provide a visual understanding of the nature of saturated liquid nitrogen flow boiling in a microgravity environment. This was undertaken by obtaining visual records of the flow patterns on film, and qualitatively analyzing them to form a definitive picture of the flow. An experimental apparatus was designed and built to obtain these visual records in microgravity. Liquid nitrogen was supplied from a dewar to an accumulator, from which it was then delivered to a test section. The accumulator was home-built and made of stainless steel. It contained a metal bellows vessel within it. Gaseous helium …
