Effect of pH on particle agglomeration and radiative transfer in nanoparticle suspensions
Al-Gebory, Layth Wadhah Ismael (2018-08)Nanoparticle suspensions (NPSs) are solid-fluid mixtures where small dielectric or metallic particles (with sizes <100 nm) used in a base fluid. NPSs have unique and tunable thermo-optical properties, and for that reason ... -
Experimental investigation of droplet impact on moving surfaces
Kayansalçık, Gökhan (2018-01)Droplet impact on moving surfaces has been studied experimentally by using high-speed photography technique. Fluid properties (droplet diameter and velocity), surface properties (wettability and roughness) and surface ... -
Immersion cooling of suspended and coated nano-phosphor particles for extending the limits of optical extraction of light emitting diodes
Tamdoğan, Enes (2017-08)Energy efficiency, long life, exceptional color and performance of solid-state light (SSL) sources have resulted in a rapidly increasing trend in a number of practical applications especially for general lighting after a ... -
An investigation into fluid flow and heat transfer of high frequency synthetic jets for electronics cooling
Ghaffari, Omidreza (2016-04)Modern electronics have been decreasing in size for decades, so their cooling systems must continually improve in efficiency too. In particular, compactness is vital, which is challenging because typical thermal management ... -
Investigation of flame characteristics in a turbulent premixed combustion
Alhumairi, Mohammed Khudhair Abbas (2018-10)In this thesis, the turbulent flame closure (TFC) model and coherent flame model (CFM) of turbulent premixed flames as steady state flow are used. In addition, large eddy simulation (LES) model as unsteady state flow is ... -
Investigation of thermal comfort performance of radiant heating systems: comparisons of different heating surface configurations
Acet, Ruşen Can (2018-02)This thesis is an experimental-numerical study for the thermal comfort assessment of radiant heating system for different heating configuration such as from a wall, ceiling and combination of both that is installed in a ... -
Limitations of passive thermal management for a-line solid state lighting technologies
İnan, Muhammed Nasır (2015-01)Energy has been one of the most important problems for the last few decades. Efficient use of energy is as important as efficiency in energy production and transportation. Solid state lighting (SSL) technology may reduce ... -
Modelling surface plasmon resonances of arrays of nano particles on a dielectric substrate using discrete dipole approximation with surface interaction (DDA-SI)
Fathi, Zahra Rastampour (2017-06)Analysis of surface plasmon resonance of arbitrary shape nano-particles on a substrate is important for many engineering applications. The strong optical absorption of noble metal nano-particles is due to the localized ... -
Performance characterization and optimization of an axial flow fan for electronic enclosures
Hashim, Hafiz Muhammad (2016-03)Thermal management of high power electronic components have become a challenging and critical issue for thermal engineers. Forced convection electronic enclosures comprises of fans to provide fluid flow through the system ... -
A preconditioned multigrid for simulation of atmospheric flow and wind turbine wakes
Jafari, S.; Başol, Altuğ; Chokani, N.; Abhari, R. S. (Elsevier, 2015-11-20)This paper demonstrates a low Mach number preconditioning formulation for high Reynolds number, low Mach number atmospheric flows. The preconditioning is implemented together with multigrid approach into a multistage solver ... -
Structural and flow relationship of microfluidics pulsating high and low frequency jets
İkhlaq, Muhammad (2015-06)Synthetic jets are being investigated last several years. Researchers have been interested in its unique applications for a wide range of flow control to thermal management of electronics applications. Synthetic jets are ... -
Thermal and radiative energy/exergy analyses of parabolic trough collector systems
Mohammed, Hayder Noori (2018-08)The concept of exergy is used to determine the maximum energy that can be extracted from a system. It is based on both the first and the second laws of thermodynamics and allows us to determine the irreversibilities ... -
Turbulence and flame interaction for control of flame location in diffuser combustor
Nazzal, Ibrahim Thamer Nazzal (2018-08)Achieving an appropriate flame location is desirable in many combustion system applications especial in the design of the combustion system. Given that the characteristics of turbulent flows influence flame behavior and ...
