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 openings are simulated to quantify the effect of flow controllers and their opening levels on mold flow. The results indicate that for a slide-gate controlled system, the meniscus velocities are significantly affected by the changes in the opening level. The steady state operations do not provide the same mold flow if the slide-gate opening is altered. However, for the stopper rod controlled system the stopper rod opening level changes do not affect the meniscus velocities and the flow structures within the mold.

Effects of stopper rod movement on mold fluid flow at Arcelormittal Dofasco's No. 1 Continuous Caster Lui, Rui; Sengupta, Joydeep; Crosbie, Donald; Yavuz, Mehmet Metin; Thomas, Brian (null; 2011-05-05) 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, part...
Effects of mean flow and temperature on acoustic liner performance in dual stream flow ducts Özyörük, Yusuf (2009-12-01) This paper investigates effects of mean flow and temperature on acoustic liner performance in dual stream flow ducts using solutions from a linearized Euler solver, which are verified with and an approximate eigenmode/mode matching technique. A simple, uniform, long cowl duct configuration with partial liner treatment on the outer wall exposed to the cold stream is studied in the present investigation. While the linearized Euler solver uses a Reynolds-Averaged Navier-Stokes solution as the mean flow, the ei...
Effect of the downstream transition region of a flow measurement flume of rectangular compound cross section on flow properties Göğüş, Mustafa; Atalay, Ahmet E. (2013-10-01) In this study, the effect of the downstream expansion region of a flow measurement flume of rectangular compound cross section on some of the flow properties; such as the discharge coefficient, C-d, the approach velocity coefficient, C and the modular limit, ML were investigated. For this reason, extensive laboratory tests were conducted with nine models of different downstream transitions. The aforementioned hydraulic quantities were then related with the relevant parameters to obtain sets of curves from w...
Effects of geometric factors on mode I fracture toughness for modified ring tests Tutluoğlu, Levend (2012-04-01) Stress intensity factors of specimen models with various external diameters, inner hole diameters, and extents of flattened loading boundaries for the modified ring testing method for mode I fracture are computed by finite element modeling. Effects of boundary conditions and geometric factors on stress intensity factor computation are analyzed. Parametric expressions are proposed to estimate critical crack length position and corresponding maximum stress intensity factor. An expression in terms of inner hol...
Effect of thickness-to-chord ratio on aerodynamics of non-slender delta wing Ghazijahani, Mohammad Sharifi; Yavuz, Mehmet Metin (2019-05-01) The effect of thickness-to-chord (t/C) ratio on aerodynamics of a non-slender delta wing with sweep angle of 45 degree is characterized in a low-speed wind tunnel using laser illuminated smoke visualization, surface pressure measurements, particle image velocimetry, and force measurements. The delta wings of t/C ratios varying from 2% to 15% with 45 degree windward beveled leading edges are tested. The results indicate that the effect of t/C ratio on flow structure is quite substantial. Considering the low ...
