Abstract
In order to create and to study the effects of liquid surface motion, a radiant strip heater which consisted of a heated rod at the focal point of a parabolic mirror was designed. Several configurations were analyzed to determine the appropriate design for a heater and it was experimentally proven that a heater with eight heated rods placed in an encasement can provide a nearly uniform heat flux on a fuel surface with magnitude varying with vertical distance. Using a heat flux gauge at various horizontal locations at a specific vertical location, the ratio of measured heat flux between the center and the outer edge of the heater was found not to exceed 1.10.
