Prediction of SO2 removal efficiency for wet Flue Gas Desulfurization
TL;DR: In this article, the SO 2 was removed by absorbing and reacting SO 2 with limestone slurry, and limestone scrubbing was accomplished in a spraying reactor Experimental investigations for effects of different operating variables on the SO2 removal showed the reasonable process parameters such as the pH value of the liquid phase, droplet size of the spray and the flow rates of liquid and gas.

Internal temperature distributions of interacting and vaporizing droplets
TL;DR: In this paper, a line of mono-sized and periodically spaced droplets is moving in the diffusion flame sustained by the droplet fuel evaporation, and the temperature field within the droplets are measured with the help of the two-color laser-induced fluorescence technique.

Bubbles, Drops, and Particles
TL;DR: In this paper, the authors evaluated the applicability of the standard κ-ϵ equations and other turbulence models with respect to their applicability in swirling, recirculating flows.
Journal ArticleDOI
Fluid Dynamics and Transport of Droplets and Sprays
TL;DR: In this article, isolated droplet vaporization, heating, and multi-component liquid droplets are discussed. But the authors focus on the behavior of droplet behavior at near critical, transcritical, and supercritical conditions.

On the theory of extraction from falling droplets II
TL;DR: In this article, the authors derived a differential equation governing the combined action of convection and diffusion for the extraction of a substance, dissolved in droplets of a fluid, when these are falling (or rising) in an other fluid under the influence of gravity.

Mass transfer in gas-liquid slurry reactors
TL;DR: A critical review on the mass transfer characteristics of gas?liquid slurry reactors is presented in this article, where the authors discuss the influence of the presence of solid particles on the following mass transfer parameters: volumetric gas? liquid mass transfer coefficients (kLa, kGa), liquid-side mass transfer coefficient (kL and kS), and specific gas?slurry contact area (a).

Circulation in liquid drops: (A heat-transfer study)
TL;DR: In this article, it was shown that circulation within a liquid drop results in an effective mass or thermal diffusivity of 2·25 times the molecular value, which is in general agreement with much reported work and with the mathematical model of K ronig and B rink which applies to liquid drops undergoing internal circulation.
