Question
Hi, i would like to know about the effect of bending a CD nozzle at its throat on the regular equations of a 2D CD nozzle. Thanks.

Answer
Ngole
You haven't given me much information on which to base my answer.  How much of a bend, 10 deg, 30 deg, 90 deg.  What geometry...?  Which equations..?
Generally, corners in ducts cause pressure loss in the flow.  The flow from corner to exhaust should not be affected, but pressures between source and exhaust will be affected.
