Abstract

The process of gas-liquid two-phase flow of an IC anaerobic reactor (25L) was simulated by fluent software. Inner Cycle Flow Rate (QIC) under different volume loading rate(OLR), ratios of riser diameter to reactor diameter(Dr/D), ratios of reactor height to diameter (H/D) were investigated respectively. The results showed that: (i) When OLR was 17.28kgCOD/ (m3•d), a maximum value of QIC (0.0099m3/h) was reached under conditions of H/D (5), Dr/D (0.081). A empirical correlation of QIC and biogas production was gained by fitting analysis; (ii)When Dr/D was 0.081, a maximum value of QIC(0.0079m3/h)was reached under conditions of OLR(11.52kgCOD/(m3•d)), H/D(5); (iii)When H/D was 3, a maximum value of QIC(0.011m3/h) was reached under conditions of OLR(17.28kgCOD/(m3•d)), Dr/D(0.081).
