Fundamental Mechanisms, Predictive Modeling, and Novel Aerospace Applications of Plasma Assisted Combustion. Overview of OSU Research Plan

Abstract

Ignition and flameholding in nonequilibrium plasma cavity flows. Objectives: * Further studies of cavity ignition and flameholding by repetitive nsec pulse plasmas in fuel injection flows (hydrogen and hydrocarbons) * High frame rate (10-20 kHz) NO and OH PLIF imaging of ignition process using burst mode laser * Increasing flow velocity beyond 100 m/sec, operating at low global equivalence ratios * Comparison with kinetic modeling calculations using reduced plasma chemical ignition mechanism. Plasma flameholding mechanism after ignition -- thermal or not? Outcome: Demonstration of true predictive capability of the model.
