Abstract: This study is a parametric investigation of the performance and operating characteristics of a cylindrical Liquid Droplet Radiator (LDR) for use in space. The LDR system mass per heat radiated was minimized as a function of the average droplet temperature at the collector. A new pump specific mass parameter defined as pump mass per liquid mass flow rate (kg/(kg/s)) was used in the total system mass calculation to develop a more physically meaningful pump specific mass term for use by design engineers.
