A model for predicting the liq. phase mass transfer coeff., kL, for the Sulzer structured packing Mellapak 250.Y and 500.Y was proposed. Exptl. data were considered together with the penetration theory. The value of kL increased with the liq. and gas flow ...
The correlations available in the literature cannot be used to est. the liq.-phase mass-transfer coeff. (kL) for viscous solns. Even correlations that agree for water-like viscosities diverge by an order of magnitude for viscosities of only 10 mPa-s. Here, ...
This two-part paper presents an overview of evaporation heat transfer mechanisms, a review of the experimental and prediction methods and a creation of a consolidated multi-lab database of 3601 data points and provides a detailed comparison of all the pred ...
We calculate numerically the normal modes of vibrations in three-dimensional jammed packings of soft spheres as a function of the packing fraction and obtain the energy diffusivity, a spectral measure of transport that controls sound propagation and therma ...
We report extensive molecular-dynamics-simulation results for binary mixtures of hard spheres for different size disparities and different mixing percentages, for packing fractions up to 0.605, and over a characteristic time interval spanning up to 5 order ...
We present exptl. results on the liq.-side mass transfer characteristics of a structured packing (Mellapak). We have measured the product of the liq.-side mass transfer coeff. kL and the effective specific area ae by the NTU-HTU method in a column of 0.295 ...
We numerically investigate the competition between phase separation and dynamical arrest in a colloidal system interacting via a short-ranged attractive potential. Equilibrium fluid configurations are quenched at two different temperatures below the critic ...
Data for the volumetric mass transfer coefficient, kLa, and the effective area, of structured packings have rarely been reported in the literature. This is despite the ever-increasing importance of structured packings in industrial separation columns for a ...
Gas absorption in packed columns was modelled, taking into account all heat effects for phys. gas absorption. Multicomponent diffusion effects were incorporated in terms of the film-factor concept. An algorithm of very stable convergence behavior was obtai ...
