Title: The Innovative Contributions of Ronald J R Dignard

Introduction

Ronald J R Dignard is a notable inventor based in Chesterville, California. He has made significant contributions to the field of fluid dynamics through his innovative designs. His work primarily focuses on the development of atomizing nozzles for fine spray and misting applications.

Latest Patents

Dignard holds a patent for an atomizing nozzle designed for mixing gaseous fluids, such as air, with liquids, such as water. This invention allows for the ejection of an atomized mist of liquid droplets. The nozzle features a body that defines three annular passages along its length. Pressurized fluid is introduced into the first annular passage, leading to a restricted annular orifice that connects to the third annular passage. Liquid is introduced into the second annular passage, with a second restricted orifice leading to the third passage. The aggressive mixing of liquid and gaseous fluid occurs in the third annular passage, where a third restricted orifice allows the mixed fluid to be forcibly ejected, atomizing the liquid into small controlled droplets.

Career Highlights

Dignard is associated with the National Research Council of Canada, where he has been able to apply his expertise in fluid dynamics. His work has contributed to advancements in various applications requiring fine misting and spraying technologies.
