Download or read book A Comparative Study of Two Computational Methods for Calculating Unsteady Transonic Flows About Oscillating Airfoils written by Donald P. Rizzetta and published by . This book was released on 1977 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a direct comparison of the calculations for the flow field about an oscillating airfoil in a transonic freestream predicted by two computational methods; namely, harmonic analysis and time integration. Details of the two methods are summarized and results for NACA64A010 airfoil oscillating in pitch are considered. Comparisons of the unsteady pressure distribution and resultant lift are presented for several values of free-stream Mach number, angle of attack, and reduced frequency of oscillation. (Author).
