Naca ducts - learn me, please

Ok, if Im getting my phrasing wrong, help me and apologies.

But Im wanting to either A) make or B) buy some naca style ducts for my cars to be able to hook up a hose or two and route it my hockey bag to dry my gear more quickly. 

My idea was to, again, either buy or build, and then build up an area around the duct to fit in my window.

Maybe it's a bad idea - if so, TELL ME! But my gear gets so stinky from the sweat sitting in it, it's not horrible if I go straight home and get a fan on it, but sometimes that ride home takes close to an hour. And sometimes I dont go home after, but out with a friend/friends etc or to the gf's house

So, is this a terrible idea?

How does it work, I mean, will air passing by the car just enter easily or is there more aerodynamics involved on racecars that make this item work?

Have a place to buy some for a good price? (I had seen one a bit back on Amazon, but it's no longer stocked, had to openings which would be really good)

Thanks ladies and gents, appreciate yall

Is it a notchback or a hatchback? 

If it's a notchback and the trunk can be sealed REALLY well against leaking to the cabin, you could run a hose from the exhaust right into the hockey bag. The hot, oxygen-free gas should be good at killing bacteria! You do have to be careful about not having a bunch of carbon monoxide go into the cabin.

I'm going to say thats a terrible idea all around.

I think a roof rack with a cage to put your bag inside will be the easiest option. 

About the actual ducts, they're called "submerged ducts". They're a low-drag way to suck air into an intake using vortices. They work best when there's nice laminar airflow along the surface. The proportions are important to make them work, as are sharp edges on the "walls" - a detail that is often lost in cheap plastic ducts. You can build your own easily enough using the dimensions developed by NACA as the information is in the public domain.

As for using it to force-dry hockey equipment, it seems a pretty extreme solution.

Thank you but I dont think I want to route in any exhaust into the car.

Keith - extreme? Maybe. But Im tempted, and I appreciate your information. It wont be a smooth surface, as there would be a bit of a raised bit just before where the pillar is (maybe half an inch?)

Thanks, again, for advice

The bump from the pillar probably won't cause enough of a disruption to keep them from working. Your car's designers probably went to some effort to keep the airflow tidy there for noise and drag reasons, which you will benefit from.

I was a goalie for a while. You want stink? Damn. And we always went out after. Because hockey and beers! Anyway you'll do best to pull everything out of the bag and lie it on a rack near a dehumidifier if you have one. Our crawlspace worked great for this. Specifically don't leave the undergarments, socks, etc in there either. Get em out and into the wash.

They do make bags with fans incorporated into them now.

I think I read a white paper written by an NHL alumni about using NACA ducts to dry uniforms and equipment...

Not.

But now I can say I've seen an inquiry which is pretty special.

The next evolution of laundry drying; Racecars!

I like this. I might do more chores if they involved racecars.

You just used a 'not' joke. ...

And of course you wouldnt hear of a NHL player doing that, they have equipment managers to handle that. 

But Im so thankful for your insightful post and try to help someone else out.

Heaven forbid someone try to use tech from the car world to improve their lives somehow. Especially something that helps cool things through forced air...much like a fan. For twenty bucks or so, I think I'll try it. But dont worry, I wont post anything 'special' about how it does or does not work

I fish in the rain for steelhead and salmon in the PNW allot during the wet season. Fishing is half the rationale for my now single seat civic hatchback that is a #vanlife with sleeping platform and other stuff to make the civic a fast 2200 lb tent good for a couple nights out in the sticks. Thus #hatchlife which doubles as a flyfishing pun!  Fish smell even worse than me or you. It's a small detail that made a big difference to the car fogging and smelling bad with piles of wet stinking fishing gear fish guts and a sweating like mad human inside but I discovered that making the rear vents (I think all modern cars have them) as exposed to the cabin as possible really helped move air.  I cut away plastic cladding to created big openings and cleared a path to the vents and then added wire mesh to keep rodents out.  Making sure the air exit is honking should help any system. 

What about taking one of your heater hoses - maybe passenger side defrost? And extending that with a vacuum cleaner hose into your hockey bag. Then have another length fished out the window. 
I mean, it's at least as classy as having a dedicated hockey NACA. 
 

haha. Good luck!

I like the idea that you have, do you have any pics of the hatch? Not just the vent area, but other mods youve made to make it a livable vehicle on your trips?

I have thought of trying to print a vent opening and running a hose that way, closing off the others. 

The key with all of this is I want something easily removable. Nothing that's there all week, just something for a day/night to go out to the beer league
