Hi @Rob 

Sorry for the late reply :), I don't have mesh actually to show you some pictures. 

The flow is incompressible, I have used ' standard initialization' for both cases ( SIMPLEC AND COUPLED schemes) 

Maybe mesh or geometry is the reason  because I have used coupled scheme for other problems of airflow in pipes 

and solution has converged ( without preventing reverse flow option)

Have a nice day
