“…The former assume the chemical reaction rate is fast relative to the transport process and the reaction rate is only dependent on the dissipation of turbulent eddies which contains the reactants [9]. The latter compares the chemical reaction rate and the eddy-dissipation reaction rate and chooses the smaller as the variation rate of reactants.…”

“…In the literature, two methodologies have been utilized: 1) modeling turbulent mixing in the absence of phase boundaries [5][6][7][8][9][10][11][12][13], and 2) microscale modeling of individual droplets immersed in supercritical or near-critical fluids [1,2,[14][15][16][17][18][19][20][21][22]. The former applies only to fully miscible conditions.…”

“…Prior studies [1,2,5,7,[9][10][11][12][13][18][19][20][21] used the ideal fluid model in computing the diffusive driving force, although the equation of state, thermodynamic and transport properties, etc., took account of the non-ideality in these studies. On the other hand, the following numerical studies used the non-ideal driving force for SCF mixtures.…”

“…With a high enough concentration of organic aqueous solution as well as the temperature above the autoignition temperature, it is possible to generate hydrothermal flames in SCWO processes. This phenomenon occurred due to the autoignition temperature of organic compound reduced under high pressure conditions (Cabeza et al, 2011(Cabeza et al, , 2013Hirosaka et al, 2007;Narayanan et al, 2008;Queiroz et al, 2013Queiroz et al, , 2015SierraPallares et al, 2009). Ignition can happen easily as the organic feeds were gaseous fuels, alcohols or other flammable organic compounds, while auxiliary fuel was required to form hydrothermal flames as with recalcitrant compounds.…”
