Improve Result of my CFD results

[Smushiehippo]

Im running a CFD simulation. Looking at improve my CFD simulation. my mesh is currently low density.

Q) Would increasing mesh density around the boundaries of the air craft wing capture the forces (velcoty & pressure) on my velocity map and added streamlines.

Yes, increasing the mesh density near the edges would increase the accuracy of the simulation. It will also slow down the simulation.
You need the greatest mesh density where the velocity of the flow changes fastest.
