Hey guys what would happen if i use coupled solver instead of segregated in case of incompressible flow problem? is it going to lead me to a wrong result or it would just take longer time but will give me the right result at last?

please reply

The coupled solver is preconditioned, so you can use it for incompressible, but it may be difficult to converge depending on the problem. At the end of the day they should both give you the same answer. The coupled solver will probably be slower per iteration, though.
