Heat transfer in magnetic fluids at low Reynolds number

Creator:: Choi, Sang Hyouk
Abstract:: This study was concerned with the flow of a magnetic self-propelled ferrohydrodynamic fluid in a horizontal circular tube subjected to axially varying temperature and magnetic field. The first phase of the study involved the analytical solution to the governing equations for the velocity and temperature profiles within the fully developed...

Full Text:: AN ABSTRACT OF THE THESIS OF Sang Hyouk Choi for the degree of Doctor of Philosophy in Mechanical

Photonic Sintering of Nanoparticle Inks : Experimental Characterization, Computational Modeling and System Design for Additive Manufacturing

Creator:: MacNeill, William D.
Abstract:: Photonic sintering of nanoparticles is a relatively new process for sintering of nanoparticles, deposited on a substrate, into functional solid structures. The working principle of this process is the incidence of large-area broad-spectrum light onto deposited nanoparticles, which results in heat generation in the nanoparticles and their subsequent densification. Key...

Finite element simulation of heat transfer in Pacific whiting surimi paste during ohmic and conventional heating

Creator:: AbuDagga, Yaser
Abstract:: The viability of using ohmic "resistance" heating as a process alternative to inactivating the heat-stable softening enzyme in Pacific whiting surimi was investigated. A fast heating rate through the enzyme-active temperature range would reduce the damage to the gelling network in surimi-based products. Simulating the ohmic heating process in surimi...

Applications of the thermal wave technique in liquid thermal conductivity measurements and flow field diagnostics

Creator:: Wang, Zhefu
Abstract:: The thermal wave technique has been explored for the use of liquid thermal conductivity measurement and flow property diagnostics in this dissertation. For liquid thermal conductivity measurements, an experimental technique based on the thermal wave approach is developed. A stainless steel strip functions as both a heating element and a...
Resource Type:: Dissertation
Full Text:: decade after the pioneering work of Masuda et al. [5]. The name “nanofluid” was first used by Choi [6

Development and Application of a Reduced Chemical Kinetics Model for Low-Speed Pre-Ignition Investigation

Creator:: Tran, Khang NV.
Abstract:: Gasoline direct injection engines, with downsized boosted technology, present a promising option for enhancing power density and reducing fuel consumption for next-generation engine designs to meet stringent fuel economy and emission standards. However, these developments in the low-speed and high-load operating regime are challenged by the occurrence of a new...

Topological Design Considering Uncertainty and Hyperelasticity

Creator:: Pham, Trung
Abstract:: Topology optimization (TO) is a mathematical method to find the optimal size, shape and connectivity of a domain under specified conditions, and has had many applications in engineering design. However, challenges remain in realizing TO as an effective design tool for many design situations. Uncertainty is ubiquitous in nature and...

Spatio – temporal temperature variations during droplet impingement evaporation : effects of nanofluid and nano-structured surface

Creator:: Graber, Christof
Abstract:: Droplet and spray impingement cooling are typically used in high heat flux thermal management. In this thesis, droplet impingement and evaporation heat transfer characteristics are determined from measured spatially- and temporally- varying fluid and surface temperatures. Unique to this study is the documentation of the effects of using a nanofluid...
Resource Type:: Masters Thesis

Modeling Methods for Hydraulic Fracturing Wastewater Treatment Applications

Creator:: O'Hern, Hannah
Abstract:: Modeling of hydraulic fracturing wastewater treatment systems must be very accurate so it can be used for real-time modeling and control of the process. The treatment of hydraulic fracturing wastewater is complex because of the variability of the composition of hydraulic fracturing wastewater. In this work, literature review of hydraulic...

An experimental study of fluid flow and heat transfer in rectangular microchannels

Creator:: Popescu, Aristotel
Resource Type:: Dissertation
Full Text:: Reynolds number. Choi et cii. (1991) measured friction factors in microtubes with inside diameters of 3

An experimental investigation of the thermomechanics of pipe flow of magnetic fluids in response to heating and applied magnetic fields

Creator:: Hamedani, Hooshyar M.
Abstract:: An experimental investigation was carried out to determine the thermodynamics and fluid mechanics of the pipe flow of magnetic fluids. A water-based magnetic fluid was synthesized in the laboratory and its relative viscosity and magnetic properties were determined as a function of temperature. A "thermomagnetic pump" was built and tested...
Resource Type:: Dissertation
Full Text:: analytical model developed for this study is based on the previous numerical work of Choi [31]. Choi's
