Analysis of core velocity in the presence of solids using UDV and improved model for cloud height in stirred tanks Fırat Taşkın, Ahmet; Uludağ, Yusuf; Ayrancı Tansık, İnci (2024-03-05) Formation of cloud height is undesired due to limited mixing between clear liquid and solids rich volume; therefore, an accurate prediction of the cloud height is crucial. In this work, ultrasound Doppler velocimetry was e...
Modelling and simulation of chemical reaction of porous MgCl2 pellets with NH3 by including impact of heat and mass transfer and structure change Helvaci, Zeynep Karakaş; Karakaş, Gürkan; Uludağ, Yusuf (2023-01-01) The MgCl2–NH3 reactive system is investigated in terms of heat and mass transfer coupled with chemical reaction through numerical simulation. The reversible nature of the chemical reaction is captured by including adsorpti...
Derişik Katı-Sıvı Karışımlarında Hız Profilinin Ultrasonik Doppler Hız Ölçüm Tekniği Kullanılarak Analizi ve Hız Profilinden Bulut Yüksekliğinin Tayini Taşkın, Ahmet Fırat; Uludağ, Yusuf; Ayrancı Tansık, İnci (2021-06-12)
Complex flow rheology analysis using Magnetic Resonance Imaging (MRI) Tezel Tanrısever, Güler Bengüsu; Mccarthy, Micheal J; Uludağ, Yusuf (2019-08-18)
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...
Theoretical and experimental investigation of ultrasound propagation through porous medium Karakaş, Zeynep; Uludağ, Yusuf (2016-08-30)
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...
