Hello there. I'm wondering if anyone could give me advice on doubling fans, piggybacking them. If one fan pulls in a certain amount of air, what would the effect be if another identical fan were behind it, screwed to the back of it using the same 4 screws? Would it double or triple the amount of air that pulls and and pushes out? What effect would this have on noise? Would it be overkill to daisy chain even 3 or 4 extra fans together I tried looking up info by going to Yahoo and typing in (airflow,"air flow") (basics,"how to",how-to) but didn't get any good results. Any feedback is appreciative.
Hi, First of all, welcome to Macmod! I don't know if you will find this info on a computer website. But as a long time Radio control pilot with ducted-fan experience, I can tell you that:
A: the turbulence created by a second fan in the air stream will negate any added flow. B: the only way to overcome this is to add stators after the first fan to straighten the flow before the second fan. And C: This adds drag and starts to make the fan duct extremely long.
In the hobby we could have as many fans as we want being driven by a nitro burning engine, but early on it was discovered to lower efficiency. Here you can see a glow powered ducted fan set up:
