Jeong and Ih [1] have investigated the sound propagation through a capillary duct with mean #ow. Numerical solutions have been found for non-isentropic acoustic disturbances with inclusion of the radial velocity terms in the governing equations and the radial velocity pro"les over a cross-section va

Flow through the spiral casing of a hydraulic turbine was analyzed. Reynolds averaged Navier -Stokes equations were solved using a finite element method. The physical domain was divided into a number of hexahedral elements which are isoparametrically mapped onto standard cubic elements. Numerical in

The sound pressure generated by a point mass monopole with arbitrary time dependence in a circular duct with uniform mean flow has been derived in the time domain. In a further step, the cross-correlation function and the cross-spectral density of the sound pressure between two microphone positions
