The Liquid Droplet Radiator (LDR) has an advantage over conventional radiators in terms of the rejected heat power-weight ratio. LDR has been taken notice as an advanced radiator for highpower generation systems which will be prerequisite for large space structures. In this study, the performance of a centrifugal droplet collector under microgravity condition has been investigated from the viewpoint of operational space use of LDR in the future. It has been concluded that (1) a centrifugal collector is able to transport working fluid to a recirculating pump under microgravity condition; (2) the ability to pump working fluid is formulated as the sum of pressure head and velocity head generated in the centrifugal collector where the velocity is c (0<c≤1) times as fast as in the rigid rotational flow; (3) splashing of the working fluid occurs at that position, when working fluid strikes against part of the entrance of the pitot tube on the centrifugal collector.
