    Packing Characterization: Mass Transfer Properties

    Get PDF
    AbstractPacking is widely used in post-combustion CO2 capture. This paper is focused on the measurement of three fundamental packing characteristics: effective gas-liquid contact area (ae), gas phase and liquid phase film mass transfer coefficient (kG) and (kL). Results show that contact area initially increases with liquid flow rate before it asymptotes to a value nearly equivalent to the nominal surface area. Initial attempts at constructing new mechanistic models have shown that existing kG and kL models can be improved. Both gas and liquid phase film mass transfer coefficients can be described as a power function of superficial gas or liquid velocity

    Positioning Performance of Power and Manual Drivers in Posterior Spinal Fusion Procedures

    This work presents an analysis and comparison of the efficacy of two methods for pedicle screw placement during posterior spinal fusion surgery. A total of 100 screws (64 manual and 36 power driven), all placed utilizing a surgical navigation system, were analyzed and compared. Final screw placement was compared to initial surgical plans using the navigation system, and the final screw locations were analyzed on the basis of angular deviation from these planned trajectories as well as screw translation within a critical reference plane. The power driver was found to insignificantly decrease the resulting angular deviation of these pedicle screws with a mean deviation of 3.35 degrees compared to 3.44 degrees with the manual driver (p=0.853). Conversely, the power driver was found to increase the translational distance in the critical region, with mean deviations of 2.45‚ÄČmm for the power driver compared to 1.54‚ÄČmm with the manual driver. The increase in translational deviation was significant (p=0.002) indicating that there may be some loss in performance from the adoption of the power driver
