Title: The Innovative Contributions of Donald P. Stubblefield
Introduction
Donald P. Stubblefield is a notable inventor based in Lake Oswego, OR (US). He has made significant contributions to the field of fluid dynamics, particularly in reducing drag on submerged surfaces. With a total of 6 patents to his name, Stubblefield's work has the potential to enhance the efficiency of surface vessels.
Latest Patents
One of Stubblefield's latest patents is an apparatus and method for reducing fluid drag on a submerged surface. This innovative design focuses on minimizing surface friction drag on the hull of a surface vessel by entraining air into the water flowing in the boundary layer along the hull. The apparatus creates a reduced pressure region by diverting a first portion of the flow away from the hull's surface. An air pocket is formed in this reduced pressure region, and a second portion of the flow is directed through the air pocket by nozzles. This action creates a plunging jet that entrains air into the boundary layer, effectively reducing drag.
