Effect of post-fill pressure and nanoclay on void morphology in resin transfer molded composites.
(2004)
Resin transfer molded (RTM) composites usually suffer from the formation of flow-induced defects such as voids. Detrimental effects of voids on performance of molded parts have been studied extensively. Yet, knowledge of ...
SHAPE DESIGN SENSITIVITY ANALYSIS AND OPTIMIZATION FOR 2-D STRUCTURAL COMPONENTS UNDER MIXED MODE FRACTURE USING EXTENDED FINITE ELEMENT METHOD AND LEVEL SET METHOD
(2009)
Weight and service life are often the two most important considerations in the design of structural components. This research incorporates a novel crack propagation analysis technique into shape optimization framework to ...
Tighter peak-to-peak performance bounds for piecewise linear systems with application to a class of semi-active control problems.
(2002)
The second major contribution is the development of a special method for determining the reachable sets for unit peak inputs associated with the six control cases of the 3-D semi-active control system. The tight bounds are ...
Transformed integral equations of radiative transfer and combined convection-radiation heat transfer enhancement with porous insert.
(2003)
In this dissertation, Chapter One has given an introduction including literature review. A modified direct integration method is presented in Chapter Two to solve 3-D radiative transfer in emitting, absorbing and ...
Break up of a round liquid jet in a low Weber number cross flow.
(2007)
The break up of a liquid jet in cross flow has applications in fuel atomization processes. The break up of a water jet in a high speed cross flow was studied with momentum ratios ranging between 10 and 172. High-speed ...
Mesoscale, porous media heat recirculating combustor.
(2005)
Small-scale power generation systems offer an alternative to traditional batteries because of the high energy density of hydrocarbon fuels. Combustion at small scales presents several challenges, including high heat loss ...
Distributed product development approaches and system for achieving optimal design.
(2006)
The research in this dissertation attempts to provide theoretic approaches and design systems to support engineers who are located in different places and belong to different teams or companies to work collaboratively to ...
Numerical study of surface tension and gravitational effects on mold filling.
(2000)
The filling process of injection molding in various planar gaps and center-gated disks are analyzed numerically. Comprehensive mathematical models are developed for flows in planar gaps and center-gated disks. An incompressible ...
An experimental and numerical study of diffusion flames in cross-flow and quiescent environment at smoke point condition.
(2003)
An experimental and numerical study of a turbulent smoke point diffusion flame in a quiescent and cross-flow condition was performed. The fuel mass flow rate of a turbulent smoke point flame was determined at a quiescent ...
Effects of elliptical burner geometry on partially premixed gas jet flames in quiescent surroundings.
(2005)
The 3:1 AR elliptical and circular burners produced similar carbon monoxide and nitric oxide emission indexes over the range of equivalence ratios of 0.55 to 4.0, for laminar flames. (Abstract shortened by UMI.)
