ABSTRACT
Solid-liquid mass transfer was studied in a trickle bed reactor packed with copper cylindrical particles. Diffusion-controlled dissolution of copper in acidified dichromate solution was used to study the solid-liquid mass transfer. The effect of liquid and gas throughputs and particle diameter on solid-liquid mass transfer was investigated.

    A point vortex is introduced into a weak background vorticity gradient at finite Reynolds number. As the vortex spreads viscously so the background vorticity becomes wrapped around it, leading to enhanced diffusion of vorticity, but also giving a feedback on the vortex and causing it to move....

    Experimentally determined mass transfer rates of the gas-liquid multiphase flow in a jet zone loop reactor are compared to several existing model approaches. The experimental data deviate due to insufficient consideration of the local hydrodynamic effects in the models. It is identified that...
