Heat transfer during the piston-cylinder expansion of a gas

Creator:: Rodrigues, Matthew Jose
Abstract:: The expansion of a gas within a piston-cylinder arrangement is studied in order to obtain a better understanding of the heat transfer which occurs during this process. While the situation of heat transfer during the expansion of a gas has received considerable attention, the process is still not very well...

Lateral fluid motion in nucleate boiling through asymmetric surface structures

Creator:: Kapsenberg, Florian
Abstract:: This thesis presents a feasibility study of a means to passively effect liquid motion parallel to a heated surface though surface geometrical modifications. Such a passive system is beneficial for electronics cooling applications as it reduces the pumping equipment normally required in flow loops and is desired for space applications,...

CFD simulation of single-phase and flow boiling in confined jet impingement with in-situ vapor extraction using two kinds of multiphase models

Creator:: He, Xiaoliang
Abstract:: With continued development of the electronic industry, the demand for highly efficient heat removal solutions requires innovative cooling technologies. A computational fluid dynamic (CFD) study, including heat transfer, is performed for an axisymmetric, confined jet impingement experiencing boiling and coupled with vapor extraction. Boiling occurs at the target surface while...

Coupled momentum and heat transport in laminar axisymmetric pipe flow of ferrofluids in non-uniform magnetic fields : theory and simulation

Creator:: Cruz-Fierro, Carlos Francisco
Abstract:: The effect of a non-uniform magnetic field on the coupled transport of momentum and heat is studied for the case of laminar pipe flow of a magnetically susceptible ferrofluid. The momentum and heat transport equations are complemented with the necessary electromagnetic terms and used to develop a computer simulation of...

Comparative methods of determining heat transfer coefficients over moist food materials

Creator:: Su, Ainong
Abstract:: Production of surimi represents a potential utilization of a number of low-valued fish species, one of which, Pacific whiting, represents the largest biomass off the West Coast of the United States. However, a protease enzyme softens the fish flesh in Pacific whiting and limits the expansion of surimi production. Many...

Effects of orifice geometry and surface boundary condition on heat transfer of impinging jet array

Creator:: Kanokjaruvijit, Koonlaya.
Abstract:: The effects of the orifice geometry and the surface boundary condition on the heat transfer distribution to a flat surface of an impinging jet array were investigated. The jet array impinged normally onto the surface which was either isothermal or had a uniform heat flux. The experiments were performed for...

Numerical design of a high-flux microchannel solar receiver

Creator:: Rymal, Charles
Abstract:: This thesis discusses the design of several microchannel solar receiver devices for use in CSP (concentrated solar power) using CFD (computational fluid dynamics) simulations. The goal is to demonstrate that, by taking advantage of the higher heat transfer coefficienct of microchannels, solar receivers can achieve higher efficiency than current receiver...

Flow characteristics of semi-confined impinging jet arrays

Creator:: Dano, Bertrand P. E.
Abstract:: The present study proposes to investigate the flow structure of different arrays of jets impinging on a flat surface enclosed by three walls, creating a channel that forces the air to leave in one preferential direction, generating a self sustain crossflow. Details of both the mean and some turbulence quantities...

A comparative study of the performance of pin finned heat sinks for cooling electronic components by natural convection

Creator:: Manolescu, Mircea Ion
Abstract:: A study was conducted to determine the heat transfer characteristics of pin finned heat sinks in natural convection. Three pin diameters were studied: 0.238 cm, 0.318 cm and 0.396 cm. The pins were attached to the base in two arrangements, triangular and rectangular, forming a horizontal array. Pin spacing was...
