If you go to the help files there is a tutorial with unsteady flow through a pipe. In this example they have a sine wave. All you need to do is change the sine wave in the udf to what ever you want i.e. a fourier series and follow the rest of the steps

You can generate a hyperbolic profile for the velocity in excel. Then, the geometry you can generate a .prof file (find the format in the help of FLUENT). Then you read the profile in FLUENT and apply this profile in the BC panel in FLUENT.
