I am doing a 2D axisymmetric simulation of a pulsating jet impingement using ANSYS Fluent.
- The geometry/mesh is a rectangular domain, with an inlet at one corner
- In the case of the steady jet, I used to simulate a separate simulation for the same diameter pipe flow, and export velocity from there to the current domain
- But in the case of pulsating jets, the velocity varies with time and space at the domain inlet
- When I apply a time-varying sinusoidal velocity profile at the inlet, I get a spatially uniform velocity profile at the inlet
- One idea is to include the pipe length in the current geometry/mesh domain, but that will increase the computational time and cost when doing parametric investigation
- Is there any way to include a spatial and temporal variation in the velocity profile at the inlet without adding a whole pipe geometry to the mesh?

Please let me know if more information is required from my side. Thank you.
