Three-dimensional single phase (liquid steel) and multi-phase (liquid steel and argon gas) k-ε turbulence models were developed to characterize the mold flow structures and to evaluate the performances of different SEN designs on different continuous casting problems at ArcelorMittal Indiana Harbor Number 2 Steel Producing Nos. 2 and 3 Slab Casters. Despite the number of assumptions introduced in CFD modeling, very good correlations between plant experiences and modeling can be achieved. In the present study, it is shown that CFD modeling can be used as a powerful tool in order to understand the experiences in plants, to explain the fundamentals of problems and solutions, to propose certain modifications that can lead to significant improvements in real caster operations, and to complement plant trials. For the Number 3 Slab Caster, the CFD modeling was performed to determine which SEN would provide higher meniscus activity to obtain better mold powder melting characteristics. For the Number 2 Slab Caster, the modeling was performed to determine which SEN would provide less defect penetration deep into the strand with more dispersed distribution. These efforts along with plant trials and water model tests, helped reduce the customer rejection rate at the Number 2 Slab Caster and improve the castability at the Number 3 Slab Caster

Liquid steel flow in continuous casting machine: Modelling and measurement Yavuz, Mehmet Metin (Informa UK Limited, 2011-08-01) Single phase (liquid steel) and two-phase (liquid steel and argon bubbles) three-dimensional computational fluid dynamic and heat transfer models were developed for the continuous casting machines of ArcelorMittal. The computational domains include tundishes, slide gates, submerged entry nozzles and moulds. The effects of buoyancy, tundish design, tundish practices, nozzle design and caster practices on flow structure were investigated. Mathematical modelling is discussed in detail. In addition, submeniscus...
Simulation of laminar microchannel flows with realistic 3D surface roughness Akbaş, Batuhan; Sert, Cüneyt; Department of Mechanical Engineering (2019) Effects of flow development and surface roughness on the pressure drop characteristics of laminar liquid flowsinside microchannels are investigated numerically using OpenFOAM. Channels with square cross section of 500 μm×500 μmand length of 80 mm are studied. Top surface of the channels are artificially roughened using thespatial frequency methodto create 8 different roughness profiles. Scaling the relative roughness ({u1D700}) values of each profile to three different values (1.0, 2.5and5.0 %),a total of 2...
CFD Modeling and Analysis of a Small Shell and tube Heat Exchanger Özden, Ender; Tarı, İlker (null; 2008-08-14) A shell-and-tube heat exchanger is modeled and numerically analyzed using a commercial finite volume CFD package. The heat exchanger is small, has a single shell and a single tube pass, and its shell side is baffled. The baffles are 25% or 36% cut single-segmental baffles. Tube layout is the staggered layout with a triangular pitch. There is no leakage from baffle orifices and no gap between the baffles and the shell. It is observed that the shell side flow and the temperature distributions are very sensiti...

Nozzle design for ArcelorMittal Dofasco's No. 1 continuous caster for minimizing sliver defects Sengupta, Joydeep; Yavuz, Mehmet Metin (2011-07-01) A study was conducted at ArcelorMlttal Dofasco to evaluate fluid flow patterns generated in the No. 1 continuous caster mold by using computational fluid flow and heat transfer models. Single-phase (liquid steel without argon co-flow), three-dimensional, computational fluid dynamics (CFD) and heat transfer models were developed using ANSYS CFXTM for a 220-mm-thick mold and a two-port SEN with a nozzle well used at the No. 1 CC to produce ULC steel slabs at various caster throughput rates. Based on these mod...
