The Effects of Blade Mistuning on Vibrational Localization

Conducted at the University of Central Florida

Mentors: Dr. Jeffrey Kauffman, Department of Mechanical & Aerospace Engineering, University of Central Florida

Abstract: In cyclic structural systems, small property irregularities, known as mistuning can often cause significant differences in the dynamics responses of their subcomponents which can result in an unpredicted premature failure of the system. Another phenomena, known as vibrational localization can also be observed as an effect of mistuning. This localization occurs when the vibration response is concentrated in a small region of the structure, in this case, turbomachinery. In this study, a MATLAB-based simulation code is used to conduct a statistics-based parameter study of mistuning where sets of coupled blades with slight mistuning were characterized in terms of a statistical distribution. A mistuning experimental setup, which accommodated nominally identical blades with coupling elements, was then developed to measure the forced response of the blades.

Summer Research

Power Law Decay in High Intensity Active-Grid Generated Turbulence

Conducted at the University of California, Irvine

Mentor: Dr. John LaRue, Department of Mechanical & Aerospace Engineering, University of California, Irvine

Abstract: Turbulent flows, unlike laminar flows, are a complex, nonlinear multiscale phenomenon making it hard to accurately predict their characteristics. In this study, we assess the power law decay of turbulent kinetic energy in a high intensity flow. Turbulent flows are important because of their ability to transport and mix fluids effectively, but their range of scales and the inherent nonlinearity in the describing equations have made it impossible to determine a general analytical solution. For this reason, much of our understanding of turbulence is based on experimental results concerning decaying homogeneous–isotropic flows, where the describing equations are relatively simple. Theory dictates that in a homogenous and isotropic flow, the dissipation of turbulence will follow a power law decay. Data is collected at a mean velocity of 6 m/s throughout the course of this experiment.
