Compressor section of gas turbine engine duct shaoes

cw1690

why convergent rather than divergent? is this to maintain the constant air velocity.
Can someone explain this better to me. Would be helpfull

I wonder why no one replied on this.

This is to take care of density increase in the flow while keeping constant axial velocity. In turbine density decreases do to expansion so passage is divergent.

Thanks for the late reply to this, I have managed to understand this now. Thanks for your help anyways
