I am trying to use frequency-wavenumber analysis to estimate sound wave propagation in a moving medium (fluid). I need to test the technique on analytical data. I wonder if there is an analytical solution that describes pressure field during sound wave propagation from a point source in a flowing fluid. I expect the pressure field to be a functin of space and time and it should shows Doppler shift effect. I am assuming a simple problem with the following assumptions:

• Fluid flow is one-dimensional.
• Fluid motion is uniform.
• Fluid is extending to infinity in both sides (i.e., boundary effects are negligible).
• Sound source is a point-source (i.e., sound source does not affect fluid flow).

I am looking for 1D solution that can estimate acousic wave amplitude as function of space ($x$) and time ($t$). I think the solution should be identical to point source which is moving in a static fluid.
