Bhattacharjee, Pratik; Riahi, Daniel N. (Department of Theoretical and Applied Mechanics (UIUC), 200512)Microgravity conditions pose unique challenges for fluid handling and heat transfer applications. By controlling (curtailing or augmenting) the buoyant and thermocapillary convection, the latter being the dominant convective ...
