The　paper　presents　an　analytical　solution　for　sound　radiated　from　the　rotating　monopole　and　dipole　point　sources　in　uniform　subsonic　axial　flow　by　employing　the　spherical　harmonic　series　expansion　method.　The　analytical　results　obtained　from　the　present　series　expansion　formulations　have　a　good　agreement　with　the　numerical　results　obtained　from　the　time-domain　and　frequency-domain　numerical　methods.　The　results　also　indicate　that　the　effect　of　the　freestream　Mach　number　on　the　directivity　pattern　is　various　for　different　types　of　the　rotating　sources.　(C)　2015　Elsevier　Ltd.　All　rights　reserved.
