transient flows
Hello friends,

I am simulating diesel engine inlet manifold.
For this i am using velocity inlet for inlets and pressure outlets for outlets.
For transient boundary conditions i am using transient profiles.In this there are negative pressures.In operation conditions i changed pressure to zero.To use absolute pressures.

But the problem is one of the outlet is changing to inlet and revers flows are occurring on the so many faces of outlets.When i am using gauge pressures the outlet remaining outlet.What is mean by revers flows and what is its effect on solution.

So please give me suggestions to overcome this problem.

Thanks in advance.
