Air entering a enclosure tends to cling to the surfaces that define the enclosure [it's called the corona effect]. By placing a screen that has a large free area [say 90% or 85%] in the lower velocity sections of the enclosure duct; will force the air to flow in the center or distribute the flow more envenly inside the duct. It will add pressure drop though. After the screen, add turning vanes to direct the flow down through the cylinders. This my solve the air distribution problems over the cylinders.
We use this method of design in air duct design.

They are used to help insure a more complete mixture of gas and air. Doug Rupert Mike, I think the purpose of vortex generators is to "create" turblent air, hence the name. If anything, you might want some baffles that smooth out and direct the airflow. Vortex generators on the wing creates a turbulent flow that helps to keep the airflow "stuck" to the wing at higher angles of attach.
