In this report, the first stage of the development process of a flow solver is presented. The solver is intended for high-fidelity simulation of wind turbine aeroacoustics. At this stage of the code development, compressible Euler solver, which has several discretization enhancements for convection term, is tested, validated and discussed. The enhancements include symmetry preservation of the discretized forms, fourth order accuracy and optimization for low-dispersion (DRP), all of which would be quite beneficial for low-level turbulence modeling and acoustic simulation problems where interference of possible numerical noise with small-scale eddies and high-frequency sound is not desired at all. The results show that the solver works at promised order of accuracy and exhibit good conservation properties, being a good start for the ultimate goal of successfully resolving turbulence and acoustic propagation.
