Mass transfer in a pulsed and non-pulsed disc and doughnut (PDD) solvent extraction column

Mass Transfer Coefficients in Pulsed Column for Separation of Samarium and Gadolinium

The mass transfer performance of a pulsed disc and doughnut column for extraction of samarium and gadolinium from aqueous nitrate solution with D2EHPA was investigated. The effects of operating parameters such as pulsation intensity, continuous and dispersed phase velocities on column performance were investigated. The axial dispersion model was used to obtain the overall mass transfer coef...

Mass Transfer Coefficients in Pulsed Perforated-plate Extraction Columns

This study examined the mass transfer performance in a pulsed perforated-plate extraction column with diameter of 50 mm using two different liquid systems. Mass transfer coefficients have been interpreted in terms of the axial diffusion model. The effects of pulsation intensity and dispersed and continuous phase velocities on the mass transfer performance have been investigated. Three different...

Investigation of Packing Effect on Mass Transfer Coefficient in a Single Drop Liquid Extraction Column

Heat and Mass Transfer in Pulsed-Laser-Induced Phase Transformations

In terms of heat transfer, the fundamental question raised in this chapter is whether essential features of pulsed laser melting and resolidification at the nanosecond time scale can be described using a thermal model. Of specific interest is the description of the transient melting front propagation as a function of the induced temperature field. Several techniques have been developed to probe...
