The idea of using capillarity as a mechanism to passively control the propellant flow in microthrusters is explored. A capillary tube consisting of two different radius sections can be employed to passively 'pump' a fluid within the tube and keep a microthruster continuously supplied with propellant. A simple, one-dimensional fluid model is developed and tested using five different fluids and five different combinations of larger and smaller radius tube sections.
