SinkScience #02 - Tesla CD Turbine and Magnetic SuperStirrer

In this SinkScience episode, Mrfixitrick shows the Tesla CD Turbine running on water-pressure, as the experimental testbed.

The spinning CD Turbine engages a magnetic coupler, rotating it. The coupler acts as a Magnetic SuperStirrer as water is impelled through it, forming a vortex in the bowl. A BIG Vortex!

Am I mistaken, or are you using magnets between the disks, and magnets below the water container to spin the disks. I'm not trying to be difficult, just trying to understand. The mass of the magnets between the disks appear to be causing the effect. Have you tried using a sheet of magnetic material, like a large refer magnet, so the bulk of the magnets were removed from the equation.I'm interested because of need for small solar powered steam turbine application. Thank-You for your patience.

@homskoult

The six magnets between each set of discs are arranged in repel mode (north up) with the 6 magnets of the stirrer (north down). That causes less "sticking" than attract mode.

A fridge magnet sheet wont work, as it will not rotate.

For more info, see my Instructables site where I have the build info for several Tesla CD Turbines. (link is in the "Show more..." window under the video.)

Messy? Its just water, and science of course. Just rearrange the magnets to act as blades.

@homskoult

I don't do normal turbines. I work with Tesla's idea of using friction, instead of working against it. Tesla used the principle of adhesion of fluid to a surface, which is a completely different idea than deflecting fluid as in a bladed turbine.

[homskoult]

Why not have the blades pull water from outer edge to center. then the water would shoot straight up.

[MrfixitRick]

@homskoult

The Tesla Turbine and Tesla Pump have no blades or cups, just smooth discs, and that is what I was demonstrating. (however, yours is an interesting idea, though it might get messy! ;)

这是一个特斯拉涡轮泵和特斯拉光盘（见汽轮机百科特斯拉），它是­用在这里创建一个漩涡示范。

在这种情况下，特斯拉磁光盘泵磁力耦合特斯拉汽轮机低于碗。

至于旋涡，我只是觉得他们让人赏心悦目！

认为这是一个更大的比如我的巨人特斯拉龙卷风圣诞树上的影片。

This is a demonstration of the Tesla Turbine and the Tesla Disc Pump (see Tesla Turbine in wikipedia), which is used here to create a vortex.

In this case, the Tesla Pump discs are magnetically coupled to a magnetic Tesla Turbine below the bowl.

As for the vortex, I simply find them fun to watch!

See my giant Tesla Tornado Christmas Tree videos as a bigger example.

不明白，你们这么多人做出个水漩涡效果来做什么用？水漩涡有什么­用处呢？

Do not understand, so many of you do to make a water vortex effects what is the use? What is the use of water swirl it?

[MrfixitRick]

@yakacm The problem is that you can only get so much power out of a faucet...a few watts at best. You could perhaps save 1 to 2 cents a day in electricity, if you ran the water full time. A sturdy turbine will cost at least $100 to make. Do the math, as they say, and it doesn't pay off. Fun factor is big, however!
