Hello Ashwin,

For adding inflation layers near the wall . You must calculate the first cell height according to reynolds number. Please check the velocity of the fluid and then according to that choose shear stress correlations and then assume y plus accordingly. Recommended 6-10 layers.

I recommend you to check these videos on how to add boundary layers
