The specification of a velocity field can help define the flow regimes that can give clues to the underlying physics, but the relevant physics depends greatly on the velocity magnitudes. There are various approaches to sound generation that are dependent upon the flow regimes, and it's impossible to focus on any particular one without knowing the governing ...

Since the flow considered represents jet mixing, it is most likely turbulent. Let us assume incompressibility of the flow at the moment for simplicity. Therefore, the Bernoulli's equation cannot be used directly to compute the pressure field given the velocity field. In order to obtain the pressure field, the Navier Stokes equation or the Poisson pressure ...
