Radial Jet Reattachment Combustion
(1993)
A novel combustion nozzle utilizing flame impingement has been developed from the concept of Radial Jet Reattachment. The RJR concept was emulated because of its high turbulence intensity and enhanced transport properties, ...
Energy considerations in active vibratory systems
(1994)
Active vibration isolation systems can generally offer substantial improvements in dynamic performance. However, their use has been limited due to the burden of cost of their implementation and operation. The cost of ...
Freeze/thaw characteristics of room temperature heat pipes-incorporating thermal history effects and non-condensible gas charging
(1993)
The freeze/thaw characteristics of room temperature heat pipes have been investigated experimentally and analytically to determine the effects of non-condensible gas loading and thermal history. Experimentally, the freeze/thaw ...
The influence of dust on the absorptivity of radiant barriers
(1993)
The purpose of this project was to model and quantify the increase of the absorptivity of radiant barriers caused by the accumulation of dust on the surface of radiant barriers. This research was the continuation of a ...
Derivation, testing and application of a new multi-scale k-e̳ turbulence model
(1991)
This study discusses the derivation and assessment of a new two-scale dissipation equation, the genesis of which begins with a different fundamental equation than previous multi-scale or single-scale models. The new approach ...
Turbulent heat/mass transfer enhancement with V-shaped ribs in a square channel
(1992)
This dissertation presents a comprehensive experimental investigation of the effects of V-shaped ribs on the heat transfer enhancement and the increased pressure drop for turbulent air flow in a square channel. The test ...
Condensation of a new alternative refrigerant flowing inside horizontal smooth tubes
(1994)
An experimental and analytical investigation of forced convective condensation in smooth circular tubes is performed for R-22 and R32+R125 mixture (50% by mass). The refrigerant is condensed by water inside a 0.315 inch ...
Development of a transient heat and mass transfer model of residential attics to predict energy savings produced by the use of radiant barriers
(1992)
A transient heat and mass transfer model was developed to predict ceiling heat gain/loss through the attic space in residences and to accurately estimate savings in cooling and heating loads produced by the use of radiant ...
Understanding molecular and macroscopic relaxation processes in model epoxy resins : theoretical and practical aspects
(1994)
In the previous phase o f this research project completely phase separated and partially phase separated bimodal epoxy resins were prepared by incorporating a 22,500 weight average molecular weight advanced epoxy resin ...
An H formulation of the QFT approach to robust performance under significant uncertainties
(1994)
The main problem investigated in this research deals with the synthesis of controllers for achieving a desired robust performance in the presence of significant plant uncertainties. The robust performance problem is ...
