Influence of mainstream turbulence and unsteady wake on turbine blade heat transfer
(1993)
The influence of mainstream turbulence and unsteady wake on turbine blade surface heat transfer was studied. The experiments were performed with a five-blade linear cascade in a low speed wind tunnel facility. The wake and ...
Thermodynamic, viscoelastic and rheological structure-property relationships of rigid poly(vinyl chloride)-styrenic copolymer blends
(1994)
In order to extend low temperature properties, rubber modification of PVC is commonly employed. The upper use temperature is however still restricted. To counter this problem modification using higher glass transition ...
System parameter analysis for robot manipulators with position-invariant natural frequencies
(1994)
The flexible PFBL (parallel-four-bar-linkage) link mechanism is designed to increase rigidity and to reduce the position variation of natural frequencies. The position variation of natural frequencies is the change of ...
Effect of backfill on the performance of a vertical U-tube ground coupled heat pump
(1995)
The present work is concerned with developing a discretized analytical model to investigate the effect of a backfill on the performance of a vertical U-tube ground-coupled heat pump. This work involves the development of ...
Development of Fourier series and Artificial Neural Network approaches to model hourly energy use in commercial buildings
(1995)
This dissertation develops Fourier series and Artificial Neural Network (ANN) approaches to model hourly energy use in commercial buildings and illustrates application to data-screening. The procedure for modeling hourly ...
Dynamic analysis of arbitrary profile liquid annular seals and transient analysis with large eccentric motion
(1993)
One of the main objectives of this work is to develop a new dynamic analysis for liquid annular seals with arbitrary profile and analyze a general distorted interstage seal of the Space Shuttle Main Engine High Pressure ...
Controller synthesis for input-output tracking in Luŕe type uncertain nonlinear systems
(1990)
A very important application of feedback is servo-tracking, or the ability of a closed-loop system to track a given class of reference input signals, while rejecting a given class of external disturbances, in the sense ...
Group combustion of coal particles
(1992)
Most practical combustor systems such as boilers, gas turbines, Diesel engines, rocket engines, etc. use liquid and/or solid fuels as the energy source. Combustion intensity is controlled by the gasification, mixing and ...
Heat transfer in a serpentine channel with a series of right angle turns
(1993)
Heat transfer in a two-dimensional serpentine channel with a series of right angle turns was investigated experimentally and numerically. Similar channel geometry can be found typically in heat exchangers, thermal regenerators, ...
Investigation of heat transfer characteristics and flow reversal phenomena in naturally convecting parallel/converging vertical channel flow
(1993)
The natural convective heat transfer characteristics in parallel/converging vertical channel flows and the flow reversal phenomena in a vertical parallel channel were studied. A sophisticated nonintrusive measurement ...
