Title: Innovations of James P Maddox

Introduction

James P Maddox is an accomplished inventor based in Van Nuys, California. He holds two patents that showcase his expertise in fluid dynamics and flow control systems. His innovative designs have contributed significantly to the fields of aerodynamics and process engineering.

Latest Patents

One of his latest patents is the "Compact Diffuser," which is designed to recover pressure from a supersonic flow with boundary layers. This invention features sharp splicer plates near the walls that form boundary layer scoops, effectively separating the flow into an inner core flow channel and outer chambers containing small supersonic ejector nozzles. The core flow, devoid of boundary layers, undergoes a single near-normal shock to recover pressure, while the boundary layers are pumped to the recovery pressure in the outer ejector chambers. The design allows for choking of the subsonic part of the boundary layer flow against the inlet corners, isolating the upstream flow. The leading edge angle of the splicers can be adjusted to help induce core flow shocking.

Another significant patent is the "Flow Control System for Erosive Fluids." This system addresses the challenges of pressure letdown and flow control in high-pressure erosive fluid streams, which may contain gas, liquid, and solid particles. Traditional throttle valves used in such applications often suffer from excessive erosion and corrosion, leading to short lifetimes. Maddox's invention employs pairs of fixed-geometry opposing nozzles whose jets meet head-on, allowing for energy dissipation and stream containment at reduced pressure. This innovative approach minimizes erosion and extends the lifespan of the components, making it suitable for various flow conditions.
