On the Calculation of Aerodynamic Diameters of Fibers [PDF]
Aerosol Science and Technology, 1985 This paper is restricted to the theoretical expressions for calculation of the aerodynamic diameters of fibers based on the viscous drag of prolate spheroids. The volume of the fibers is calculated either by the expression for a cylinder (Harris and Fraser, 1976) or the expression for a prolate spheroid (Khalik and Gonda, 1984). Perpendicular, parallel,

Aerodynamics via acoustics - Application of acoustic formulas for aerodynamic calculations [PDF]
10th Aeroacoustics Conference, 1986 Prediction of aerodynamic loads on bodies in arbitrary motion is considered from an acoustic point of view, i.e., in a frame of reference fixed in the undisturbed medium. An inhomogeneous wave equation which governs the disturbance pressure is constructed and solved formally using generalized function theory.
