Abstract Details

2007, PhD, University of Cincinnati, Engineering : Aerospace Engineering.
The design and development of high performance turbomachinery operating in both ambient and high temperature environment in the presence of solid particles requires a thorough knowledge of the fundamental phenomena associated with particulate flow. Because of the serious consequences of turbomachinery erosion on their performance and life expectancy, it is important to have reliable methods for predicting their erosion when solid particles are ingested with the incoming flow. The ingestion of these solid particles over a period of time will reduce the efficiency of the propulsion system, causing increased fuel consumption and reduction in performance and thrust. Many studies, essential to predicting blade surface erosion intensity and pattern, have been conducted at the University of Cincinnati’s Propulsion Laboratory in the past. The studies and experiments at the (UC) laboratory were performed in order to obtain a better understanding and a more realistic prediction of erosion rates of various conventional materials and coatings, while varying impingement angle, particle velocity, particle concentration, particle size, temperature and other important erosion parameters. Solid particle erosion is a complicated process which becomes even more complicated when it comes to composite material structures. In composite materials the mechanisms of erosion are complex, difficult to determine and even more difficult to predict due to the non-homogeneity of the material. Attempts were made to understand some of the basic mechanisms of erosion as early as the beginning of the (20th) century and continue even today. Over the years most of the attention of scientists was concentrated toward understanding the mechanisms occurring in conventional materials. However, due to the growing potential of composite materials and their desirable properties, they became a more focal point of interest.
