Computational Fluid Dynamics Analysis Of An Ideal Anguilliform Swimming Motion, Charles Rogers Dec 2014

Computational Fluid Dynamics Analysis Of An Ideal Anguilliform Swimming Motion, Charles Rogers

University of New Orleans Theses and Dissertations

There is an ongoing interest in analyzing the flow characteristics of swimming fish. Biology has resulted in some very efficient motions and formulating these motions is of interest to engineers. One such theory was written by Dr. William Vorus and Dr. Brandon Taravella involving ideal efficiency. It is therefore interesting to test the calculations to see if it is possible to design a motion that can create thrust without necessarily creating vorticity. The computational fluid dynamics software of ANSYS Fluent was used to calculate the resulting flow field of the eel motion to compare with the theoretical values.

Measuring Enrichment Liability In The Context Of Unfinished Construction Projects, Aimite Jorge Dec 2014

Measuring Enrichment Liability In The Context Of Unfinished Construction Projects, Aimite Jorge

Aimite Jorge

Abstract: Most aspects of construction projects mainly fall under contractual regime. However, when things go wrong such as when the project is abandoned for various reasons, they may create two different scenarios: a contract that is breached and a fixed structure that is left on the land which may constitute an incomplete benefit that is acquired by one of the parties. The transfer of such benefit is initially made with a legal ground, but that ground has since ceased to exist. If some aspect of that benefit cannot be recovered under a contract, enrichment rules may be competent to solve ...


Determination Of Area Of Fire Origin Through Examination Of Structural Failure And Deformation, Andrew Thomas Tinsley Dec 2014

Determination Of Area Of Fire Origin Through Examination Of Structural Failure And Deformation, Andrew Thomas Tinsley

Doctoral Dissertations

The effects of fire on steel have long been noted and studied. However, a scientific connection between the area of origin for a fire and the amount of steel deformation observed at the scene has never been established. The development and implementation of this type of analysis has the potential to decrease investigation times significantly as the types of structures to which this method would be applicable are typically large, expansive structures. In order to investigate the relationship between structural steel deformations and a fire’s origin, a series of six tests were performed in a smaller size portal frame ...

Shock Pulse Filtering Evaluation On Package Size And Cost, Matthew P. Daum Ph.D. Sep 2014

Shock Pulse Filtering Evaluation On Package Size And Cost, Matthew P. Daum Ph.D.

Journal of Applied Packaging Research

Distribution packaging design often relies on cushion curves to determine required material thickness needed for product protection during shipment. The material thickness chosen based on cushion curves establishes overall package size, a key determiner of logistics costs. Cushion curves are constructed by dropping a mass onto a cushion, and interpreting the resulting shock pulse deceleration. The reported deceleration can be highly influenced by applying a “filter” to the shock pulse, a useful standar d prac - tice that removes unwanted high frequency elements superimposed on top of the basic shock pulse shape. Standard test methods for generating cushion curves generally do ...
