I am setting up a test-bed for an experiment. Here's what I have.
A circular car exhaust like this Image
The gas comes out of the exhaust at a velocity, x.
We need to lower the gas velocity to X/3
- The 'reducer' should exert very less backpressure on the flow
What possible directions should I look into, if you know any pre-filters, baffles, geometries that can help me reduce the flow rate in minimum size, that'd be awesome.
