THE COANDA EFFECT

Even if you've never heard of the coanda effect before, you'll undoubtably have experienced in in some form at least.

What is it?

The coanda effect is the action in fluid mechanics whereby a flow along a solid surface tends to follow the curvature of the surface rather than separating.

Quick example.

Imagine you we're to pour tea from a teapot, but do it really slowly.

What happens?

Rather than simply pouring out at a slow rate as expected, the liquid will stick to the teapot, and dribble down the spout instead.

This is the coanda effect in action, and it plays a role in longboarding too.

THE COANDA EFFECT AND LONGBOARDING

The coanda effect - alongside the way longboards are shaped - helps to keep your board gripped into the wave face, also exhibiting a downward pressure on the rail of the board which assists with nose-riding.

The more downward pressure on the board, the bigger imbalance is created, which makes nose-riding easier.

WRAPPING IT UP

The coanda effect is just one of a group of forces that need to be harnessed to make nose-riding possible.

And if you didn't know about it, now you do. And now you can begin to see the3 bigger picture of how nose-rideing is possible.
