I've got baffles in my RC and PC... They're the extra bits of solder that dribbled down the tubes due to my dodgy soldering skills. :doh:
Whether or not you get laminar flow will depend on the smoothness of the surfaces inside the condenser and the flow rate. Faster flow rates cause turbulent flow.
I also have employed this precision design of solder blobs in my condensers :laughing-rolling:
The first one I made also has loose bits that didn't stick to anything when they fell thru which I like to think adds some turbulence. When you turn it upside down it sounds like a rain stick :laughing-rolling:
Seriously though the other thing you can do is have your inlet and outlet on opposite sides
