    Abstract
  • Effects of design parameters on hydrogen-oxygen coaxial injector discharge coefficient were investigated by hot tests and numerical analysis.Experimental and theoretical analysis results are in good agreement.The deeper recess length of liquid post leads to smaller injector discharge coefficients of oxygen and hydrogen.The larger annular gap leads to a greater oxygen discharge coefficient but a smaller hydrogen discharge coefficient.
