Latest Patents

Among his latest patents is a groundbreaking "Method for enhancing mass transport in fuel deoxygenation systems." This invention features a fuel system designed for energy conversion devices, incorporating a deoxygenator system with a multitude of flow impingement elements. These elements are strategically interleaved to provide intricate two-dimensional flow characteristics, efficiently breaking up boundary layers and enhancing the transport of oxygen within the fuel flow. By directing the flow normal to the oxygen-permeable membrane, his system accelerates the mixing of oxygen, thereby improving the overall removal rate of oxygen from the fuel without incurring significant pressure drops.

Another notable patent is the "Discharge diffuser for screw compressor." This invention includes a housing that features an inlet for receiving flow from a compressor and an outlet, aptly defining a collector, transition, and diffuser portion. It is designed to manage a plurality of non-parallel streams from the compressor, transforming them into a substantially parallel flow direction. The integrated splitter plate further separates these streams, helping in the reduction of flow losses.
