Theoretical investigations on heat transfer to H2O/CO2 mixtures in supercritical region

Potential and challenges for the new method supercritical CO2/H2O mixed fluid huff-n-puff in shale oil EOR

“…Supercritical fluid can not only be used as reaction medium in chemical reaction, but also directly participate in reaction. Supercritical fluid can change the phase behavior, diffusion rate and solvation effect, homogenize the reaction mixture and increase the diffusion coefficient (Heltai et al, 2002;Yang et al, 2019;Chen et al, 2020), thus controlling the phase separation process and the distribution of products. When ScH 2 O is used as the reaction medium, its specific physical and chemical properties will affect the progress of the reaction.…”

“…In addition, some scholars have studied the convective heat transfer characteristics of supercritical fluid mixture. Chen et al [204] found through numerical simulation that the mixed fluid of S-CO 2 and supercritical water has similar heat transfer behavior with supercritical water at the critical point of water, and the forced convection heat transfer coefficient of these supercritical mixed fluids can be accurately predicted by using the correlation proposed by Jackson [205]. Zhang et al [206] verified through experiments that the heat transfer mode of the mixed fluid of supercritical water and S-CO 2 is similar to that of supercritical pure fluid in supercritical region.…”
