A tubular rheometry that is based on obtaining velocity profiles by nuclear magnetic resonance imaging (NMRI) and measuring pressure drop of the flow is used for the polymer melts. This technique allows one to get viscosity data potentially over many decades of shear rate region in a single measurement. In this study, we examined polyethylene melt as the flow medium. Despite the low shear rates attained, our results reveal that this non-invasive and non-destructive method is promising for constructing an on-line polymer melt rheometer.

Magnetic Resonance Signal Analysis in Inhomogenous Magnetic Fields
Arpinar, V. E.; Eyüboğlu, Behçet Murat (2009-09-12)
Nuclear Magnetic Resonance (NMR) systems with inhomogenous main magnetic fields have been satisfactorily used to explore material properties. So that, imaging of biological tissues using Magnetic Resonance Imaging (MRI) systems with inhomogenous main magnetic fields could be explored. In this work, magnetic resonance (MR) signal deviation due to inhomogeneity in the main magnetic field of a MRI system is investigated. This analysis gives the understanding of the effect of inhomogeneity in magnetic field to ...
Magnetohydrodynamic Flow Imaging Using Spin-Echo Pulse Sequence
Eroğlu, Hasan Hüseyin; SADIGHI, MEHDI; Eyüboğlu, Behçet Murat (2019-04-24)
In this study, magnetohydrodynamic (MHD) flow of conductive liquids due to injection of electrical current during magnetic resonance imaging (MRI) is investigated. A spin-echo based MRI pulse sequence is proposed to image the MHD flow. Magnetic resonance (MR) phase effects of the MHD flow is related to the MRI pulse parameters and injected current. Average velocity distributions of the MHD flow are reconstructed using the MR phase images. The method is validated by numerical simulations. The reconstruction ...
Magnetic Resonance Electrical Impedance Tomography For Anisotropic Conductivity Imaging
Degirmenci, E.; Eyüboğlu, Behçet Murat (2008-11-27)
Magnetic Resonance Electrical Impedance Tomography (MREIT) brings high resolution imaging of true conductivity distribution to reality. MREIT images are reconstructed based on measurements of current density distribution and a surface potential value, induced by an externally applied current flow. Since biological tissues may be anisotropic, isotropic conductivity assumption, as it is adopted in most of MREIT reconstruction algorithms, introduces reconstruction inaccuracy. In this study, a novel algorithm i...
Anisotropic Conductivity Imaging with MREIT Using J-substitution and Hybrid J-substitution Algorithms
Degirmenci, E.; Eyüboğlu, Behçet Murat (2009-09-12)
Magnetic Resonance Electrical Impedance Tomography (MREIT) is a tomographical imaging technique which uses measurements of magnetic flux density induced by a probing current to reconstruct electrical conductivity distribution within a conductor object with magnetic resonance active nuclei. In this study, two novel anisotropic conductivity reconstruction algorithms for MREIT are proposed. The technique is evaluated with simulated measurements.
Computational Modeling of the Effects of Viscous Dissipation on Polymer Melt Flow Behavior During Injection Molding Process in Plane Channels
Tutar, M.; Karakuş, Ali (2013-02-01)
The present finite volume method based fluid flow solutions investigate the boundary-layer flow and heat transfer characteristics of polymer melt flow in a rectangular plane channel in the presence of the effect of viscous dissipation and heat transfer by considering the viscosity and density variations in the flow. For different inflow velocity boundary conditions and the injection polymer melt temperatures, the viscous dissipation effects on the velocity and temperature distributions are studied extensive...
