A short video animation from NASA on airflow changes against nose gear and nose gear doors:

Always useful to compare with the 90 degree airflow turn that is illustrated in the manuals under “aero piston engine cooling”.
Is it just me or is this one of the rare cases where science matches with intuition perfectly? I mean come on, nobody could seriously expect the airflow to radically alter its direction suddenly, right?
Sometimes it does that, for instance when it enters a Cirrus Turbo intake duct, it reverses course and flows away from engine suction, and causes the alternate air box flap to freeze shut.
Free stream flow is something else altogether than flow in a confined space.
Please expand. Do laws of physics change when in a confined space?

Do you think that I think that you think they do?

Perhaps that’s the problem, the ‘airflow’ is in fact stationary at least in an integrated sense. Then the plane comes a long and moves it every which way as the animation shows.
