aerodynamic theory

aerodynamic theory

generally accepted theory that the vibration of the vocal folds in phonation is produced by the flow of exhaled air past lightly approximated vocal folds; opposed to the now untenable concept that vocal fold motion in phonation results from contraction of the intrinsic muscles of the larynx at the frequency of the vocal fold vibration.

Titze has published more than 400 articles in scientific and educational journals, coedited two books titled Vocal Fold Physiology, and now has three books in print: Principles of Voice Production, The Myoelastic Aerodynamic Theory of Phonotion, and Fascinations with the Human Voice.
Using the aerodynamic theory of wind turbine airfoils and blades, they introduce a conformal transformation, propose parametric optimization design methods for different airfoil series with maximum thickness of 12-40%, and validate the aerodynamic performance by wind tunnel experiments.
Some of the constraints and parameter limits were set based on geometric/rules restrictions; the remaining parameter limits were set based on multi-element aerodynamic theory [16, 17].
With the traditional aerodynamic theory on a finite wing with no sweep, the induced velocity generated by its own bound vortex at an arbitrary location along the lifting line can be ignored.
Many researches have been done in the analysis of panel flutter in supersonic flow (Ma < 5) using the linear aerodynamic theory such as the first-order piston theory [1-5] or linearized potential flow theory [6-8].
This has encouraged the belief that the Germans were ahead of the rest of the world in aerodynamic theory and that the adoption of swept-back wings in the next generation of fast jets was due to German theoretical advances being taken over by their former enemies once they had won the war and were able to pillage German laboratories.
He examines both the basic and applied aspects of aerodynamic theory for students, engineers, and applied physicists, combining theoretical analysis, physical features, and application aspects.
In chapter 10, the author concludes by giving a sociological, even philosophical commentary on the development of aerodynamic theory and the interactions, both theoretical and human.
