Modeling large temperature swings in heat regenerators using orthogonal collocation

Creator:: Kokron, Carlos J.
Abstract:: This thesis examines the transient performance of packed bed heat regenerators when very large temperature differences are involved. The effects of gas temperature on the key gas physical properties of velocity, density and heat capacity were studied via simulation. Three models were developed and compared. The first model (HRKDV) considers...

Modeling a heat regenerator-reactor with temperature dependent gas properties

Creator:: Kulkarni, Milind S.
Abstract:: This thesis examines the transient response of a packed bed heat regenerator when heated from an initial uniform bed temperature. Very large (1700 K) temperature differences were studied as well as the effect of simultaneous chemical reaction in the gas phase. First the effects of temperature on physical and transport...

Investigations concerning heat transfer involving wedge-shaped configurations

Creator:: King, John Michael
Abstract:: The temperature field inside a "truncated" wedge is investigated. For this purpose the two dimensional Green's function of the heat equation for this domain is established. Further applications of these results center around a problem of heat conduction investigated by Lebedev.

Dynamic modeling of a refrigerant boiler for power applications

Creator:: Curry, Thomas Haitsch
Abstract:: A dynamic model of a refrigerant boiler has been produced by the use of distributed parameter modeling techniques. A number of elementary cases were studied and were used as an aid in the final model formulation. Modeling using distributed parameters employed the use of mesh equations which were then reorganized...

Performance of rotary regenerative heat exchanger--a numerical simulation

Creator:: Bae, Young Lib
Abstract:: This thesis examines the transient and steady-state temperature performance of a rotary regenerative heat exchanger. In contrast to previous studies on this problem, fluid flow in the circumferential direction was considered. Appropriate modeling was included to measure the effect of carry-over on the differential equations describing mass and energy conservation....

Laminar natural convection within long vertical uniformly heated parallel-plate channels and circular tubes

Creator:: Vorayos, Nat
Abstract:: The problem of simple mathematical models of laminar natural convective flow within a long vertical parallel-plate channels and circular tubes kept at uniformly heated walls is revisited to seek a clear physical understanding of heat transfer mechanisms. A series solution method to analyze the fully developed flow and an integral...

A study of micro-scale, fractal-like branching flow networks for reduced pumping power and improved temperature uniformity

Creator:: Alharbi, Ali Y.
Abstract:: A first generation, one-dimensional predictive model is proposed for designing heat sinks with fractal flow networks. A three-dimensional computational fluid dynamics (CFD) model is analyzed as a means for validating the model and identifying areas for improvement. Two separate CFD models were developed. One was analyzed with conjugate heat transfer...

Numerical study of natural convection in square partitioned and non-partitioned enclosures

Creator:: Sukkaset, Prasart
Abstract:: Heat transfer characteristics and associated temperature and flow fields for natural convection in two-dimensional, square, partitioned and non-partitioned enclosures have been determined for Grashof numbers ranging from 10³ to 10⁶. The vertical side walls of the enclosure are isothermal with all other surfaces assumed to be adiabatic. An adiabatic partition...
