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...
The flow configurations around and the forces acting on a
circular cylinder with its axis parallel to a nearby plane boundary
and subjected to a uniform flow were investigated. The flow conditions,
which were perpendicular to the cylinder axis and parallel to
the plane boundary were investigated experimentally and theoretically....
The engineering design process and the advancement of future computer-aided-design systems need new design aids to be used during the conceptual design phase. This design phase is where information gathering and understanding of the problem are developed, analyzed and broken into small more manageable elements. These elements consist of customer...
A number of computational tools now exist to aid in developing conceptual solutions based on a functional description of a design problem. A key limitation of these tools is the way results are organized for presentation to the user. In general, results are an undifferentiated mass of potential solutions. Analysis...
Manufacturing technology has continuously evolved and advanced over the past century; this has led to an increase in the production of consumer and industrial goods driven by simultaneous growth in population and wealth. Despite the resulting economic and labor growth, environmental impacts of manufacturing have increased dramatically due to the...
This thesis reports on research conducted to determine
the information which should be included in a mechanical
design history. This is part of a larger research effort
aimed at developing a computer tool for storing and
replaying mechanical design history information. Three
question-asking protocols were conducted to determine what
information...
This work explores a framework for the gathering and analysis of information rich customer needs, with the goal of informing inclusive product design practice. The goal is to be able to provide information and experience to designers so that they can better understand the needs of exceptional users and include...
The Lyapunov direct method is utilized to determine the
robustness bounds for nonlinear, time-variant uncertainies
p[subscript i]. Determination of the robustness bounds consists of two
principal steps: (i) generation of a Lyapunov function and
(ii) determination of the bounds based on the generated
Lyapunov function. Presently in robustness investigations,
a...
