His innovative work has implications for various applications in aerospace and propulsion systems.

Latest Patents

Gutmark's latest patents include a solid fuel ramjet combustor and a dump combustor with noncoherent flow. The solid fuel ramjet combustor patent describes a mechanism where a fluid flow boundary layer extends along a burning fuel grain, receiving combustible material liberated from the grain. This process excites oscillations in the air flowing toward the grain, promoting vortices that enhance the mixing of air and combustible material. The dump combustor patent outlines a design where the flow area for fuel and air increases suddenly at the dump, generating vortices that mix the fuel and air for combustion downstream. The unique aspect of this design is that the flow cross-section upstream of the dump is noncircular, which results in aperiodic mixing and uniform heat release.
