Improved Design and Manufacture of of Generalized Flow Profile-Producing Devices
The StreamVane device covered by utility patent application 14795545 (VTIP-2014-137US) is an original device for the generation of desired pressure and swirl profiles in a flow. In recent work, we have found that the addition of a wire screen device to a StreamVane produces an increased degree of flexibility for the generation of desired flow profiles....

Design and Manufacture of Generalized Flow Profile-Producing Devices (Stream Vane)
A new method for the design and manufacture of flow conditioning devices has been developed. The devices are capable of producing any desired outlet flow profile consisting of total pressure and flow angle (swirl) distributions. The method utilizes new computational procedures for the aerodynamic and mechanical design of the device, providing improved...

Premixing Injectors for Gaseous Hydrogen Combustion in Gas Turbines
Low nitrogen oxide (NOx) emission is a goal for both power generation and aero propulsion gas turbines. The invention described here allows for the lean premixed injection of a gaseous hydrogen/air mixture into the combustor of a gas turbine. The combustible mixture produced is predicted to have a uniformly distributed fuel-to-air mass ratio at the...

Improved Electric Plasma Torch for Ignition, Flameholding and Enhancement of Combustion in High Speed Flows
In the quest for successful combustion in high-speed flows with minimal shock losses, technology has been developed and implemented in Mach 2.4 cold flow at Virginia Tech. The flush-wall design avoids physical obstructions such as ramps, vanes, struts, etc. for liquid fuel injection, utilizing a unique injection/atomization technique which simultaneously...
