Sentences with phrase «turbulent air flows»

At the planet's equator is a layer of turbulent air flow, which smoothes out at higher latitudes, notes Fred Taylor, a University of Oxford physicist and interdisciplinary scientist for the Venus Express mission.

«In contrast the Brazuca, with its deeper grooves, hits that turbulent air flow at a lower speed with the result that the ball is much more predictable.

The group also measures the turbulent air flow to understand how it interacts with the drifting snow.

This is the world's first draught - stop system that enables different comfort levels to be selected for two occupants, as the driver and passenger can individually pivot the units to the centre of the vehicle in a flash, thus taming turbulent air flow from the rear.

To my eyes, it seemed that there was still quite a lot of turbulent air flowing around the body of the Civic, but the quality of my aerodynamic analysis could be one of the reasons why I shoot cars for a living rather than design them.

There's also Airguide, a new draught - stop system consisting of pivoting transparent plastic layers attached to the reverse of the roll - over bars — the driver or passenger can swing them to the centre of the vehicle in a flash to tame turbulent air flow.

Not exact matches

That thin layer of turbulence acts as a lubricant that allows the rest of the air to flow smoothly all the way around the ball, minimizing the size of the turbulent wake and the drag — a phenomenon known as the drag crisis.

«By sensing gusts and disturbances in air flow through their feathers, birds are able to fly gracefully rather than bouncing around in turbulent air,» he said.

Turbulent air generates considerably more drag than smooth - flowing (laminar) air.

So while the general idea of turbulence in air is correct, your calculation underestimates the tendency for turbulent flow.

Using the Reynolds number above in your calculation, you can see that turbulent flow in air would happen (at a height of 1m above ground) at a velocity of 0.0315 m / s.

The air itself is mainly just limiting the rate of heat loss, more turbulent mixing and a higher flow rate just enhances the rate of loss.

Personally, I don't think the difference between turbulent and laminar flow is all that significant for this issue: In either case, you're going to be mixing air of one temperature («outside») with air of another («inside»).
