Why did the Mythbuster's dimple car get better fuel economy?
I'm trying to understand why the Mythbuster's dimple car gets better fuel economy - if it actually would as I'm not
I understand that a golf ball functions by creating turbulent air flow and via the ...

Governors and acceleration effect on IC engine
If a car is moving with a constant velocity this means that resistive loads (like air drag friction) should equal the driving force from the car; but I know that the governors always cancel the effect ...

What are the practical applications of Centre of Mass & Centre of Gravity?
I have learnt COM and COG are different things if we have non uniform gravitational field i.e. mass will be same at anywhere but gravity will be different. I want to find practical examples of both ...

What affects a car's overall top speed?
I've always wanted to know how a car's top speed could be determined. Usually, I thought it was horsepower and aerodynamic drag. I learned that weight can affect top speed, but I've recently found out ...

How do drag and downforce in a rear spoiler of a car vary with angle of attack?
I ran an two aerodynamic simulations, one for a spoiler angle of 0 deg and the other for the same spoiler declined at 30 deg. The results showed a considerable increase in downforce, but only a slight ...

Scanning and modeling my personal vehicle for aerodynamic simulation
I have this pickup truck that I love dearly. I often change the aerodynamic configuration of the truck when I use my camper shell, or roof top tent, etc.
Is there a reasonably easy way to create a ...

Why do some cars have flow channels in their bodies to decrease drag?
From my understanding, the more surface area the flow passes, the more drag happens due to skin friction.
An example of this is the new Ford GT, which has a converging cockpit and separated side body ...

Aerodynamical forces - downforce
I have heard that car weight (for more friction = more stability and higher traction) is being increased when driving by a force called aerodynamic down-force which causes additional force on the car ...
