“…The experimentally measured t m in the SDR above appeared to be much longer than those in other rotating reactors, such as the rotating packed bed (RPB). The t m in RPBs was reported to range from 0.2 to 0.8, 0.1 to 1 s, and be less than 0.5 s, which demonstrated that the mean residence time was usually in milliseconds under the enormous centrifugal field . Such a considerable positive discrepancy should be derived from the experimental setup of the outlet sample points for measuring the residence time.…”

Residence time distribution (RTD) is an essential hydrodynamic prerequisite for the appropriate modeling of reactors. Our previous study designed a spinning disk reactor (SDR) for intensifying photochemical processes with disk configurations of elliptic-cylindrical spoilers (ES) and cylindrical spoilers (CS). Herein, RTD of the tailored SDRs was numerically studied using a pulse input method after verification with experimentally measured RTD curves in the previous literature. Mean residence time (t m ) and dimensionless variance (σ θ 2 ) of the SDRs were in ranges of 0.29−1.43 s and 0.02−0.15, respectively. t m and σ θ 2 were higher in the SDR with ES and CS than in the SDR with a flat disk. The nonideal flow behavior was assessed through tanksin-series (TIS) and axial dispersion models. TIS (n) and Peclet numbers (Pe) were, respectively, in ranges of 10−70 and 10−150 for the SDR with spoilers, indicating a departure tendency from plug flow. Finally, based on the simulation results, correlations of n and Pe relative to physical properties and operating parameters were established with deviations less than ±20%.
