Abstract: A system for dispersing a catalyst in a fuel includes a first reservoir containing the fuel, and a second reservoir including an agitator and containing a quantity of the catalyst suspended in the fuel. The system also includes a first conduit extending from the first reservoir, a second conduit extending from the second reservoir, and a mixing nozzle connected to the first conduit and the second conduit. The mixing nozzle includes a first meter positioned within the first conduit, a second meter positioned within the second conduit, a valve positioned upstream from the second meter within the second conduit, a junction in flow communication with the first conduit and the second conduit, a mixer downstream from the junction, a sensor positioned between the mixer and an outlet; and a controller connected to the valve and the first and second meters, the controller receiving feedback from the sensor.

Abstract: A method of making a part including a solid portion with an internal passage includes building the part using an additive manufacturing process that builds the part on a layer-by-layer basis. The solid portion of the part is formed. Forming the solid portion includes fusing the solid portion. A solid core is formed within at least a portion of the internal passage. Forming the solid core includes fusing the solid core and forming an attachment feature on the solid core. Material that is not fused, either semi-sintered or un-sintered, is positioned between the solid portion and the solid core. At least a tensile, compressive, vibratory, or torsional force is applied to the solid core at the attachment feature. The solid core is then removed from the part.
