NASA is planning future missions not only to send robotic landers as far as Europa but also land humans on Mars. To develop advanced aircraft capable of such long-duration missions, spacecraft thermal control technology needs to become more compact, have high efficiency, and have low weight and volume. Traditional thermal management systems have relied heavily on single-phase air and liquid cooling designs. However, these systems cannot meet the heat dissipation needs necessary for future long-term space missions.
We are exploring better thermal management systems for space systems by utilizing two-phase flows because of their higher heat transfer performance over single-phase flows. Our research spans from fundamental studies in two-phase flows to understand the effect of reduced gravity on boiling, condensation heat transfer and critical heat flux, to technology development investigations in terms of new innovative concepts for heat pipes relevant to in-space applications. Because these studies are helping us develop a better understanding of the effect of gravity, we are also interested in research in hypergravity which is relevant to fighter aircrafts.
