Latest Patents

Cormack's latest patent is titled "Method and apparatus for improved mixing in fluids." This invention provides an apparatus and method for accomplishing fluid disinfection by passing fluid flow through a uniform array of ultraviolet lamps. These lamps have cross sections that are perpendicular to the direction of fluid flow, defining channels for the fluid. Positioned next to the end of each lamp at the entrance of the fluid flow are triangular-shaped delta wings. These wings have surfaces inclined at an angle to the direction of fluid flow. The interaction of the fluid flow with each delta wing creates a pair of vortices that can rotate in the same direction or in opposing directions. The counter-rotating vortices reinforce each other, minimizing the dissipation of their mixing strength as they move down the channel. This co-reinforcing property promotes efficient mixing of the fluid, which is essential for maximizing the use of light in UV disinfection systems, as well as enhancing heat and mass transfer in chemical reactions. Although described in the context of a UV reactor system, this invention is applicable to other types of arrayed flow systems where increased fluid mixing is desired.
