Title: Innovations of Roy E Pack, Jr.
Introduction
Roy E Pack, Jr. is an accomplished inventor based in Winterset, IA (US). He holds a total of 2 patents that showcase his innovative contributions to the field of fluid dynamics and combustion technology. His work is particularly relevant in applications involving gas turbine engines.
Latest Patents
One of his latest patents is the Aspirating Simplex Spray Nozzle. This innovative spray nozzle is designed to produce a spray or mist containing a high concentration of bubbles. Such a spray is particularly useful in mixing liquid fuel and air for burning within a combustion chamber, as for example in a gas turbine engine. The novel design includes a pair of swirl chambers generally axially aligned within the nozzle. Fuel or other liquid enters the first or forward swirl chamber in a generally tangential and laminar flow pattern, passes into the second or rearward chamber through an interconnecting orifice. Violent liquid and air mixing occurs in the second chamber, and the mixture is then expelled as an aerated spray through the interconnecting orifice, the first chamber, and a discharge orifice.
Another significant patent is related to fluid metering and spraying. This invention involves an orifice and nozzle for the passage of fluid that may contain solid particulates as contaminants. The orifice and nozzle includes an opening that is rectangular in a cross-sectional plane perpendicular to the axis of fluid flow. The rectangular opening has a ratio of minimum width to minimum depth, or vice versa, of less than approximately 1.5, and preferably 1.0. Additionally, the ratio of the length of the opening to the lesser of minimum width and minimum depth of the opening is less than approximately 2.0, and preferably 1.0. This unique design prevents plugging by solid contaminants, enhancing the efficiency of fluid flow.
