TL;DR: In this article, a numerical analysis of the quasi-steady fluid flow and interfacial behavior in a three-phase argon gas-stirred ladle with off-centered bottom Ar injection through a plug and two plugs placed in 1808 and 908 configurations, respectively, is presented.
Abstract: A numerical investigation is performed to describe the quasi-steady fluid flow and interfacial behavior in a three-phase argon gas-stirred ladle with off-centered bottom Ar injection through a plug and two plugs placed in 1808 and 908configurations, respectively. The flow of the fluid phase is solved in an Eulerian frame of reference together with the motion of every individually injected Ar bubble, tracked in its own Lagrangian frame. Volumeof fluid (VOF)modelis usedtotrackanyinterfacebetween twoor moreimmisciblephases,whichincludeslag/metal, slag/gasandmetal/ gas. The characteristics of fluid flow in a gas-stirred ladle with one plug or two plugs configuration are described when the slag layer and the top gas are presented. The slag layer deformation and slag open-eye formation at different Ar gas flow rates for three types of plug arrangements are given. The comparison of the mixing time, the deformation of slag layer and the behavior of slag/steel interface between one-plug and twoplug system is made. Several implications for ladle operational issues during a gas-stirred ladle refining cycle are discussed. It is found that the proper selection of Ar gas flow rate and plug arrangements during a ladle refining cycle is required for different refining purposes considering the mixing and metallurgical reaction in a three-phase ladle system.

TL;DR: In this paper, the authors performed direct numerical simulations in order to study physical and reactive absorption in gas-liquid flow on structured packing and found that the mass transfer is affected by the complex geometry considered here and by the flow conditions.

TL;DR: In this article, the authors proposed a rotor consisting of a bulk fluid chamber containing a bulk amount of fluid and a metering chamber which has a predetermined volume, which is delivered to the receiving chamber through an exit duct.
Abstract: The present invention provides a centrifugal rotor which measures and delivers a predetermined volume of fluid to a receiving chamber in the rotor. The rotor comprises a bulk fluid chamber containing a bulk amount of fluid and a metering chamber which has a predetermined volume. The bulk fluid flowing into the metering chamber fills the chamber and excess fluid flows out into an overflow chamber. Thus, a predetermined volume is obtained. This volume is delivered to the receiving chamber through an exit duct which prevents flow at the rotational speed required to fill the metering chamber but allows flow at a second, higher rotational speed. The exit duct is typically a capillary in which capillary forces prevent flow until the rotational speed is increased.
