Explain venturi tunnel design

I know what they are and why they're used etc. I just can't find any solid info about their design.

Air that is sped up has less pressure, so the tunnel design speeds up the air, sucking the car to the ground..

Okay, is the tunnel 4 sided or is the ground the 4th side and side skirting helps maintain the seal?

I read about the inverted wing design implemented in a venturi tunnel. Then sometimes another tunnel seems to narrow side to side-speeding up the air that way.

Is there one basic design? Or do some tunnels simply have an inverted wing design while others narrow?

Point me towards an article with some good pictures or drawings please.
