DEP-Enhanced Micro-Injector Array for Liquid Fuel Atomizer

MicroEnergy Technologies, Inc. (mET), collaboratively with Technology Assessment and Transfer, Inc. (TA&T) proposes to develop an injector array for liquid fuel atomization. This development effort hinges upon the application of a novel system of parallelensemble of dielectrophoretically (DEP) enhanced micro-injectors. Using an electric field, the spray process is controlled precisely to match the high response time demand of pulsed detonation propulsion systems and other liquid fuel air-breathingengines. Using micro-injectors of smaller than 100 micron provides the fine mist desirable for optimal mixing and combustion. The proposed atomizer offers a number of advantages over the current and state-of-the-art technologies that exist for liquidatomization: (1) It requires low driving pressure (~10 psi) and significant weight savings (smaller pump and less bulky construction to sustain high hydraulic pressures), (2) System design requires simple
