Tunable near-field radiative transfer by III-V group compound semiconductors Elcioglu, Elif Begum; Didari, Azadeh; Okutucu Özyurt, Hanife Tuba; MENGÜÇ, MUSTAFA PINAR (IOP Publishing, 2019-03-06) Near-field radiative transfer (NFRT) refers to the energy transfer mechanism which takes place between media separated by distances comparable to or much smaller than the dominant wavelength of emission. NFRT is due to the...
Near-field radiative transfer in spectrally tunable double-layer phonon-polaritonic metamaterials Didari, Azadeh; Elçioğlu, Elif Begüm; Okutucu Özyurt, Hanife Tuba; Mengüç, M. Pinar (Elsevier BV, 2018-6) Understanding of near-field radiative transfer is crucial for many advanced applications such as nanoscale energy harvesting, nano-manufacturing, thermal imaging, and radiative cooling. Near-field radiative transfer has be...
Gold-in-Water Nanofluids in Microchannels: Surfactant Effect Şimşek, Eylül; Redmond, Matthew; Koyuncuoğlu, Aziz; Okutucu Özyurt, Hanife Tuba; Külah, Haluk (null; 2018-05-25) Heat transfer and pressure drop performance of gold-in-water nanofluids in microchannels are experimentallyinvestigated. Gold nanoparticles are suspended in de-ionized (DI) water. The nanofluid stability is maintained bypo...
Modeling and analysis of surface roughness of microchannels produced by mu-WEDM using an ANN and Taguchi method Jafari, Rahim; Kahya, Muge; Oliaei, Samad Nadimi Bavil; ÜNVER, HAKKI ÖZGÜR; Okutucu Özyurt, Hanife Tuba (2017-11-01) Microchannel heat exchangers are used to remove the high heat fluxes generated in compact electronic devices. The roughness of the microchannels has a significant effect on the heat transfer characteristics, especially the...

Entropy generation analysis of a microchannel-condenser for use in a vapor compression refrigeration cycle Turkakar, Goker; Okutucu Özyurt, Hanife Tuba; Kandlikar, Satish G. (2016-10-01) Dimensionless entropy generation number in the microchannel condenser of a vapor compression refrigeration cycle is investigated. An air cooled, brazed aluminum parallel flow heat exchanger is considered as the condenser w...
Numerical simulation of flow boiling from an artificial cavity in a microchannel Jafari, Rahim; Okutucu Özyurt, Hanife Tuba (2016-06-01) Cahn Hilliard phase-field method is used to numerically simulate subcooled water boiling in which nucleation occurs from an artificial cavity on the inner surface of a microchannel. The boiling initiates from a cavity and ...
Investigation of warpage behavior of single crystal silicon on a silicon Adhesive ceramic integrated structure at cryogenic temperatures Baloğlu, Can; Okutucu Özyurt, Hanife Tuba; Dursunkaya, Zafer (2016-03-17) Understanding thermal stress and warpage behavior of heterogeneous component assemblies is vital in infrared sensor applications of silicon semiconductor material. The silicon semiconductor warpage behavior of the integrat...
3D numerical modeling of boiling in a microchannel by arbitrary Lagrangian-Eulerian (ALE) method Jafari, Rahim; Okutucu Özyurt, Hanife Tuba (2016-01-01) The arbitrary Lagrangian-Eulerian method (ALE) is used to model the hydrodynamics and the heat transfer of an elongated vaporized bubble in a rnicrotube. The Navier-Stokes equations along with the energy equation are solve...
An experimental study on the dispersion stability of alumina-water nanofluids via particle size distribution and zeta potential measurements Elcioglu, Elif Begum; Okutucu Özyurt, Hanife Tuba (2016-01-01) The concept nanofluids have attracted attention due to the possibility of gaining increments in transport properties including thermal conductivity. While such increments have been verified to some extent, their maintenanc...
