Automotive Aerodynamics (video series)
Hey guys,

I recently started a video series on automotive aerodynamics. During my research for each episode, I am often directed to this forum. So I thought I'd share my findings, enjoy!

Welcome !
Great to have you here.

Thank you, I look forward to any input and constructive criticism (suggestions) for future episodes

Quite a contrast between the garage (the one with the oriental rug on the floor. Can you get your car in there?) and the water tunnel (how many horsepower does that consume?) How do you get access to the water tunnel? Will you graduate and have it go away or do you have a permanent job there.

Did you see Yoshi Suzuka's work before it disappeared from Youtube?

I notice in Automotive Aerodynamics Future Episode Preview! you are soliciting models for testing. I built this in 1995, but I'd let you thrash on it:

Anyways, I guess I know where the next few hours are going, even though it's sunny outside. :thumbup:

Can you measure forces in the water tunnel? If so, do you see expected increases / decreases in drag, when adding spoilers onto models?

Great idea for a video series!

My initial suggestion, in this era of shortened attention spans, is on episode length.

I'm only partway through one (surprise: I chose the shortest one to view first... then again, that's because I should be working :) ) and it's fantastically info dense! If your goal is a seminar-type program (and I suspect it is), that's fantastic. But if your goal is widest viewership, it may be a drawback.

But now I know what I'll be doing for another couple of hours in the near future.

Obvious suggestion (if it hasn't been made yet): examination of some DIY drag-reduction mods, as found throughout our aero subforum.

Also: welcome to the forum!

Awesome! Only watched the first video so far but looking forward to the rest!

Briefly sampled a few more. Just fantastic - this thread is going on the front page.

(FYI, future replies to this thread bump it to the top of the list.)

I'm in between classes right now so I only watched the first 5 minutes of the first video but the series looks awesome!

Is it possible to add miniature tufts to the car models for tuft testing, or is water too dense to show this accurately ?

( I'm currently halfway through the first video, so i may have missed any tuft testing if you did it later in the series. )
