Abstract

We report quantitative composition data on continuous jet-mixing of ethanol with ambient carbon-dioxide (CO2) at temperatures (T=[313 K–333 K]) and pressures (p=[9 MPa to 11 MPa]) in the vicinity of the mixture critical pressure of the binary system. Progress of mixing is quantified simultaneously on the macro- and on the micro-scale. The lag between mixing on both scales is quantified spatially resolved and in the jet-mixing region. We found that surprisingly mixing below the mixture critical pressure in the two-phase mixing regime can be more efficient than mixing above the mixture critical pressure in the single-phase mixing regime. Density was the key parameter influencing the mixing efficiency.
