Compressible flow structures interaction with a two-dimensional ejector: a cold-flow study [PDF]
, 2009 An experimental study has been conducted to examine the interaction of compressible flow structures such as shocks and vortices with a two-dimensional ejector geometry using a shock-tube facility. Three diaphragm pressure ratios ofP4 =P1 = 4, 8, and 12

Optical investigations on hydrogen/methane‑oxygen flame diluted by steam in micro-mixing burners
Fuel Processing TechnologyMotivated by the goal of zero-emission power generation, the current paper investigates the micro-mixing combustion of hydrogen/methane and oxygen under steam diluted conditions, over a range of oxygen mole fraction (0.05–0.5) and hydrogen blending power

Electrode erosion in steady-state electric propulsion engines [PDF]
The anode and cathode of a 30 kW class arcjet engine were sectioned and analyzed. This arcjet was operated for a total time of 573 hr at power levels between 25 and 30 kW with ammonia at flow rates of 0.25 and 0.27 gm/s.
