Abstract A model of turbulent multiphase flow, heat transfer, and particle entrapment during continuous casting steel is presented. The includes the top 7m vertical curved strand, considers effects argon gas injection thermal buoyancy. RANS flow results are compared with LES. Lagrangian transport through Eulerian-Eulerian field from k -ɛ based on random walk features advanced capture criteria, ...

Background and Objectives: Despite superior privileges that multiphase motors offer in comparison with their three-phase counterparts, in the field of multiphase linear induction motors (LIMs) few studies have been reported until now. To combine the advantages of both multiphase motors and linear induction motors, this paper concentrates on multiphase LIM drives considering the end effects. Met...

The mechanics of the cutting process on the microscopic level differ fundamentally from the conventional macro cutting. For example, the tool edge radius influences the cutting mechanism in micro machining significantly with regard to the effective rake angle, the minimum chip thickness, the dominance of ploughing, and the related elasto-plastic deformation of the workpiece material. These phen...

In this work, the fluid dynamic and thermal behavior of steel was analyzed during argon gas stirring in a 140-t refining ladle. The Eulerian multiphase mathematical model used conjunction with discrete ordinates (DO) radiation steel-slag-argon system. validated by particle image velocimetry (PIV) analysis opening oil layer physical scale model. effect Al2O3 Mg-C as refractory walls studied, Ran...

The role of direct numerical simulations (DNS) of multiphase flows, where all continuum length and time scales are fully resolved, in validation and verification of models for the average flow, is discussed. Although DNS are usually limited to relatively small problems and are generally impractical for predictions of full-scale multiphase systems, DNS offer unprecedented data and insight. Indee...

The application of different structural materials to manufacture basic parts drying units various types was analyzed. It has been established that surface erosion resulting from solid par-ticles' impact is a serious problem for many industrial equipment using multiphase flow. shown the value rate depends on local particle velocity and angle can be calculated software Ansys Fluent 18. principles...

The multiphase leisure experience looks at the experience as a five phase process that includes anticipation, travel to, onsite behavior, travel from, and recollection. This continuum depicts a dynamic experience, one that evolves and matures across the five phases. The purpose of this study is to take this model and apply it to sport events. Understanding sport events as a multiphase experienc...

Design and Analysis of Multiphase DC-DC Converters with Coupled Inductors. (May 2007) Meng Shi, B.Eng., Shanghai Jiao Tong University, China Chair of Advisory Committee: Dr. Prasad Enjeti In this thesis, coupled inductors have been applied to multiphase DC-DC converters. Detailed analysis has been done to investigate the benefits of directly coupled inductors and inversely coupled inductors, co...

Although good agreement with experiments was MACROSEGREGATION in large steel ingots is one achieved, the model relied on many approximations (such of the most well-known and now classical problems in the as estimating the flow velocities). It should also be menfield of solidification and casting.[1] It arises from the relative tioned that many models have appeared in the literature ...

In the past, the two major biomineralization motifs, biosilicification and biocalcification, were considered as two discrete processes. However, there is increasing evidence of the existence of an inextricable relationship between biosilica and calcium-based biominerals. The recent discovery of a unique silica–chitin–aragonite biocomposite in one genus of demosponges (Verongida) introduces a no...
