Stress behavioursof viscoelastic flowaround square cylinder
Tezel Tanrısever, Güler Bengüsu; Yapıcı, Kerim; Uludağ, Yusuf (2019-06-01)
In this study, it is aimed the numerically investigation of the flow of liner PTT (Phan-Thien-Tanner) fluid, which is a viscoelastic fluid model over limited square obstacle by finite volume method. The finite volume metho...
Flow Characterization of Viscoelastic Fluids around Square Obstacle
Tezel, Guler Bengusu; YAPICI, Kerim; Uludağ, Yusuf (Periodica Polytechnica Budapest University of Technology and Economics, 2019-01-01)
This study focuses on the computational implementation of structured non-uniform finite volume method for the 2-D laminar flow of viscoelastic fluid past a square section of cylinder in a confined channel with a blockage r...
Numerical and Experimental Investigation of Newtonian Flow around a Confined Square Cylinder
Tezel, Guler Bengusu; YAPICI, Kerim; Uludağ, Yusuf (Periodica Polytechnica Budapest University of Technology and Economics, 2019-01-01)
The confined flow of a Newtonian fluid around a square cylinder mounted in a rectangular channel was investigated both numerically and experimentally. Ratio between the pipe and channel height, the blockage ratio, is kept ...
DEPENDENCY OF NANOFLUID RHEOLOGY ON PARTICLE SIZE AND CONCENTRATION OF VARIOUS METAL OXIDE NANOPARTICLES
YAPICI, Kerim; Osturk, Ozge; Uludağ, Yusuf (FapUNIFESP (SciELO), 2018-04-01)
Impact of the nanoparticle size and concentration on the rheology of ethylene glycol based nanofluids containing nanoparticles of five different metal oxides is investigated. Particle mass concentrations ranged from 5 to 2...

Rheological characterization of polyethylene glycol based TiO2 nanofluids
YAPICI, KERİM; KEKLİKCİOĞLU ÇAKMAK, NEŞE; Ilhan, Naciye; Uludağ, Yusuf (2014-11-01)
Rheological characterization of TiO2 nanoparticle dispersions in polyethylene glycol (PEG 200) is presented over 1-10 wt% particle mass fraction range in terms of shear viscosity, thixotropy and linear viscoelasticity. A s...
Utilization of I-Q signals of ultrasound Doppler velocimeter to obtain 1-D turbulence quantities in pipe flow
KÖSELİ, VOLKAN; Uludağ, Yusuf (2014-10-01)
A new method based on using inphase-quadrature (I-Q) ultrasound (US) signals was developed in order to overcome time resolution limitations encountered in turbulent flow measurements by ultrasound Doppler velocimetry (UDV)...
Theoretical and experimental investigation of fluid rheology effects on modulated ultrasound propagation
Ozkok, Okan; Uludağ, Yusuf (2014-09-01)
A mathematical model is developed and presented to capture the effect of viscoelastic nature of a material on modulated ultrasound (US) pulses. The model is established by considering perturbation of material elements subj...
