Hello everyone,

I am trying to simulate a free circular jet @ reynolds number =1850.
proceeded with both steady and transient state.

I am attaching the image of the grid and boundary conditions.

Solutions are converging but it is not capturing the kelvin helmhotz instabilty .

Frequency of oscillation computed experimentally is 300 Hz.

Time step that is used in transient case = 10^-4.

Pressure based solver used.

Kindly help if i m wrong with the boundary conditions.
