You mean the jet penetration is too low? Please zoom in and show the mesh.

Replot with node values off, and then tell me why you think the jet should penetrate the domain with that level of mesh refinement.

So if my mesh is much finer, will the jet propagate more?

Not necessarily, but with a coarse mesh you'll see far more false/numerical diffusion. Most courses teach y+ for meshing to the exclusion of all else. They neglect to mention that you must also resolve the farfield and all flow features. Repost the image, and then tell me how well you think the jet is resolved.

Boost Ansys Fluent Simulations with AWS
Computational Fluid Dynamics (CFD) helps engineers design products in which the flow of fluid components is a significant challenge. These different use cases often require large complex models to solve on a traditional workstation. Click here to join this event to learn how to leverage Ansys Fluids on the cloud, thanks to Ansys Gateway powered by AWS.
