Is the width of the bell immediately after the opening important to be wider 4 to 5 times or just the CSA of the bell should be be 4 to 5 times more than the opening area? The area in a horizontal plane directly after the inlet opening is the crucial factor.

I have this question, important for me right now, if the outlet to the chimney or one bell to another has same CSA but is made of several slots like in a heat exchanger, will it work the same, will the draft be ok?

Could work ok, but only could. Friction and boundary layer doesn't help turbulence neither. Why would you want to do this?

I thought of recovering more heat by giving the gases more surface in the area where they are suppose to go up the chimney but instead take the additional energy that would otherwise be wasted without an additional bell
