Abstract
The resupply technique of cryogenic liquid propellants under microgravity condition is a key technology to construct an infrastructure of space transportation system. Our study is on investigation of forced convective boiling of the cryogenic fluid for establishment of this technique. In the present experiment, we used the transparent heated tube, which can allow temperature measurements and visual recordings at the same time. It was conducted under Ig and microgravity (10^<-5>g) using Japan Microgravity Center (JAMIC). We succeeded in measuring heat flux and heat transfer coefficient on forced convective boiling of LN_2 using the tube under Ig and microgravity.
