In the presented work, a new numerical approach to computational aeroacoustic (CAA) problems based on a modified total variation diminishing (TVD) scheme is examined in order to investigate its value as a possible alternative to the more computationally expensive schemes currently used in CAA. Such schemes generally rely on high-order dispersionrelation-preserving (DRP) algorithms. The method is applied to the direct numerical analysis of an unsteady, compressible, viscous 2-D flow over a cylinder at a Mach number of 0.5 and a diameterbased Reynolds number of 100,000. The acoustic signal is extracted directly from the unsteady flowfield solution at several radii and compared to the acoustic predictions based on the Potential-Theoretical Method.
