An 'empty' zone

January 5, 2002, 16:35

I'm working on opposed jets simulation. The model is very simple: 6-degrees sector is the computational zone (for the problem is axisymmetric); the boundary types used are: inlet (2), pressure (outlet) and walls (2). The certain part of the region remains 'empty' (zero scalars concentration and negative relative pressure). Should I treat this region in some special way? The problem is that the obtained temperatures are ~x2 higher then expected.

If you are combusting will you have some recirculation present keeping it hot from the flame convection into it?

Excuse me, can you explain your question?
