"In doing the analysis, I learned how considering a reduced order model using the dominant modes allowed me to understand the dynamics and the important physics of the process without unsteadiness and noise that is present in the data. The laminar flow wing is usually thinner than the conventional airfoil, the leading edge is more pointed and its upper and lower surfaces are nearly symmetrical. Laminar flow airfoils attempt to keep the boundary layer laminar from the l. Laminar flow airfoils were originally developed for the purpose of making an airplane fly faster.

"From the class, I learned how to use modal analysis techniques, in particular, proper orthogonal decomposition, and how the technique can help me understand the dominant modes and dominant features in the flow in question," Collazo Garcia said. Turbulent and laminar flow airfoils are designed with different goals in mind. The paper was developed for the course AE 598-Modal Analysis of Fluid Flow taught by Theresa Saxton-Fox, assistant professor in the Department of Aerospace Engineering at the University of Illinois Urbana-Champaign. The beauty of this technique is it takes out all of the random noise-all of the uncertainty associated with the data-and identifies the modes that are most important so we can more efficiently study the process." During the design of this airfoil, special emphasis was placed on experiences and observations gleaned from other successful general-aviation airfoils. A review of the NACA and NASA low-drag airfoil research is presented with particular emphasis given to the development of mechanical high-lift flap systems. Worse still, a specially designed laminar wing can exhibit abrupt changes in airplane handling when laminar flow breaks down. The modes provided a snapshot of various aspects of the flow and were ranked by their energy contribution, with the higher-ranking modes showing the most important characteristics of the flow. Airfoils, Inc., State College, Pennsylvania 16803 A natural-laminar-flow airfoil, the NLF(I)-01l5, has been recently designed for general-aviation aircraft at the NASA Langley Research Center. This paper proposes a novel design optimization method for transonic natural-laminar-flow (NLF) airfoils allowing for suppressing crossflow instability. "I was able to apply linear algebra techniques to manipulate the flow field data and decompose the information into modes. However, given the speeds and conditions that airplanes encounter, trying to maintain laminar flow is difficult. For streamlined bodies, such as airplanes, maintaining laminar boundary layer airflow is a sure way to minimize drag and so improve efficiency and reduce fuel costs. Laminar flow (also known as streamlined flow) is characterized by air flowing in a smooth linear fashion over a surface of the wing.

"When I got the assignment to do a research project, I realized I already had a good data set from my master's thesis that I could use in a new way," Collazo Garcia said. CFD Simulation of Laminar Flow Over An Airfoil Velocity Magnitude Contours.
