| dc.description.abstract | A steady state transonic airfoil analysis code has been modified to include the presence of a vortex near the airfoil. The objective was to provide quasi-steady analysis of blade/vortex interaction for studying or predicting impulsive rotor noise. Results of BVI in low speed flows compare well with the results of incompressible methods in both lift coefficients and pressure distributions. In high speed flows, the code breaks down in the fine grid near the center of the vortex because the program does not model a compressible vortex. The code must be altered to correctly model the flow near the center of the vortex before it will be useful in the study of impulsive rotor noise. | en |
