Effects of stopper rod movement on transient flow phenomena in the mold and formation of sliver defects are investigated via plant measurements and numerical simulations. First, sliver locations are correlated with stopper rod position and level fluctuation histories in the mold by analyzing images of slivers and process data recorded at ArcelorMittal Dofasco's No.1 Continuous Caster. Then, 3D transient CFD models are developed, validated with plant measurements, and applied to simulate transient flow, particle motion, and entrapment phenomena to reveal how level fluctuations arise, and how the slivers may have formed.

Effect of Flow Rate Controllers and their Opening Levels on Liquid Steel Flow in Continuous Casting Mold Gursoy, Kadir Ali; Yavuz, Mehmet Metin (2016-01-01) The present study investigates the mold flow structure at constant throughput condition for different slide-gate and stopper rod openings by utilizing computational fluid dynamic (CFD) modeling. Detailed validation of the CFD models are conducted using available experimental data and the performances of three different turbulence models, standard k-epsilon, realizable k-epsilon and k-omega SST are compared. The constant throughput casting operations for different slide-gate and stopper rod controller openin...
Effect of boundary conditions and workpiece geometry on residual stresses and microstructure in quenching process Gür, Cemil Hakan; Schuler, W (1996-11-01) In this study, the internal and residual stress states in quenched C60 steel cylinders are analyzed both numerically and experimentally in order to investigate the effects of boundary conditions (such as quench severity and temperature of quench bath) and specimen geometry Specimen geometry has been analyzed by introducing a hole in a cylinder arid varying hole diameter and its' eccentricity. In the numerical analysis, the finite element method is applied and both temperature gradients and Phase transformat...
Effects of optical design modifications on thermal performance of a highly reflective HfO2/SiO2/TiO2 three material coating OCAK, M.; Sert, Cüneyt; Okutucu-Ozyurt, T. (Springer Science and Business Media LLC, 2018-02-01) Effects of layer thickness modifications on laser induced temperature distribution inside three material, highly reflective thin film coatings are studied with numerical simulations. As a base design, a 21 layer coating composed of HfO2, SiO2 and TiO2 layers of quarter wave thickness is considered. First, the laser induced temperature distribution in this base design is obtained. Then the layer thicknesses of the base design are modified and the corresponding temperature distributions in four alternative no...
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...
Effects of glass fiber reinforcement and thermoplastic elastomer blending on the mechanical performance of polylactide Varsavas, S. Deniz; Kaynak, Cevdet (2018-06-01) The purpose of this study was to investigate how optimum mechanical properties (strength-modulus-toughness) of inherently very brittle polylactide (PLA) could be obtained by reinforcing with E-glass fibers (GF) and blending with thermoplastic polyurethane elastomer (TPU). Composites and blends were compounded by twin-screw extruder melt mixing, while specimens were shaped by injection molding. SEM analyses revealed that 15 wt% GF and 10 wt% TPU domains, alone and together, could be uniformly distributed in ...
