I've noted that there is much energy in the amount of mass spinning in a TT.
The larger the disk pack, the more energy stored.  I read an article on
flywheel stored energy.  Got me thinking - higher rpm, higher velocity fluid
stream, magnetic bearings, composite materials able to handle steam - pretty
good combination.

Surely, some of you noticed how long it takes to spin down a TT.  Thats a
lot of energy return thats usable and should be put into the equation of
energy return when considering efficiencies (especially if you take into
account the energy expense of spinning up the rotar).

Anyone else putting the flywheel notion to TT?  I don't recall anyone
touting high rpms typical in flywheels.

Where does one learn about the tesla turbine an how to build it?

More direct info:
http://www.eskimo.com/~ghawk/rotary.html

I agree that this is interesting for energy conversion.  However, I have a
friend who used to be a funny car driver.  He said that direct conversion of
water to steam in the combustion chamber creates some very high energy water
molecules that eat away pistons.  The steam damage is incredible so he says.
Someone else in this list might back me up on this.

The article mentions Brown's gas.  When I read the patent on the Brown's gas
it was intended for implosion.  The H2O decomposed to 2H2 + O2 and then
recombined to release energy, then take away the energy and the gas becomes
water which is a reduction of volume of some 1700 to 1.  Pretty impressive
vacuumes can be made that way.  Brown's gas was important for the correct
mixture of hydrogen and oxygen so there won't be left over gases resulting
in higher ambient final pressure.

I would suggest direct steam production in an external combustion chamber.
Especially one that is easily serviced to replace the liner.  Then direct
the pressure/velocity of the combustion products to the TT rotar.

Hi

Found this while searching for "Cold Fog"

Brinsbury Hydrogen Steam Rotary Engine
A rotor revolves with no reciprocating pistons. Water and hydrogen are
injected and ignited. The heat turns the water vapor into high pressure
steam on each power stroke. The power is derived from the steam expansion
with the hydrogen as the internal heat source. This being the reverse of the
present steam engine, where a large body of water is heated externally. They
are said to be interested in investors.

http://www.eskimo.com/~ghawk/email_rotary.htm

Worth a look to see if the idea could be adapted for the turbine.

I'm new here, so i'll start with a hello to everyone.

Let me introduce myself first im a Norwegian with to much time on my
hands

I was wondering if anyone knows where i can find useable data
regarding bladeless turbines and air.

I am planning an experiment to see if I can build a bladeless turbo.
So if anyone has any information or data applying this to air
compression etc. I would be extremely interested.

I will use ceramics since my new vacuum controlled atmosphere furnace
is finally installed (I had to wait 6 months for the bloody power
supply) I can now create ceramics with pyrolised polymer foam and
chemical vapour infiltration, cool.

And also does anyone know a good supplier of ceramic ball bearings?

Kent

<envy>What a setup.  Maybe you could make some turbine parts to sell to the
list.</envy>

I have a set of drawings that I scrapped because ceramics cost too much.
You are welcome to them.  They are designed specifically for ceramic disks,
housing, washers and a metal shaft.  I have nothing for the nozzle.

Welcome to the list.  I'm working on my second runner pack of CD ROMs to
experiment with compressed air.  I've just about finished the runner.  I
have materials for the housing.  I made the compressed air storage tank, but
it leaks at the joint so I have to plug a hole.  My goals are to measure
P.E. in and K.E. out.  After making changes, hopefully improvements, I'll
repeat the measurements.  This cycle will continue until I have a maximum
efficiency at designed opperating speed.  Then I'll work on stored energy
and maximum efficiency to start the runner from 0.

I would go with all the prior suggestions and recommend building a standard
TT before making modifications.  There is much to be learned in the
experience of building the basic turbine.  I'm learning a lot.

Mr Passerotti

Thank you for the offer I would appreciate the drawings, I did some
tests with commercial ceramics but the test disk flew apart
(literally disintegrated) above 20k Rpm so to get more tensile
strength I decided to try with composite ceramics instead since they
have much higher tensile strength.
To buy custom composite shapes from a manufacturer costs an arm and a
leg and since I want to try out different options I decided to buy
the manufacturing kit myself it wasn't all that expensive actually I
made some parts myself and only bought the high tech end vacuum pumps
safety valves etc.

If I manage to make a safe prototype I will offer parts for sale to
the group.

I look forward to seeing your plans

Hi

I know this question probably has been asked time and time again.
But just for the record can someone point me in the right direction.

I am trying to find a site or information for calculations to do with the
Tesla Turbine and what relationship there is between:

1. Disc diameter
2. Port size
3. Number of discs

Also some indication of air consumption as I plan to build a vehicle powered
by compressed air using a Tesla Turbine.

I have been looking at several types of air motor and plan to build a few to
do some comparison tests.

I am not an armchair physicist so am not interested in someone telling why
it wont work or that its not viable.

I have found some reasonably detailed information at:

http://tesla.stemwinder.org/.

The "Qualitative analysis" is the best technical discussion I've seen --
it's the only web resource I've found that relates to actual science rather
than wishful thinking.

There's also an undergraduate thesis which is useful as a step-by-step guide
to building a turbine -- too bad the result didn't work.  Also on the
non-working list is the tesla turbine spreadsheet -- which would have been
really useful.  :-(

I have more sitting here too, but I have to scan them in.
I'll post here when I get around to it :)  If someone bugs me
it'll go faster :)

Hi all,
I posted Qualitative analysis by Glen Barlis (2001)
in Files. Its 75k wordpad doc. Very good and to the
point.
If I understand Glen correctly and Im not an engineer
major. This turbine needs to be "tuned" or designed
around a specific input, pressure and fluid or gas type.

If not the efficiency can suffer so much that its
pointless to build this machine.

Tesla's turbine has some good points, mainly its simple
design lends durability, longevity, maintainability
and possibly lower cost.
I am working with heated refridgerants (170-190 deg F)
solar and gas. Rankine cycle. I wouldnt even begin to
design a turbine until I have the pressure and volume
of input finalized.

the thesis and a working xls spread sheet is available in the archives......

Hi All,
HELP!!!
I,ve got as far as the nozzle design for my steam TT and have ground
to a halt due to lack of available info.
Questions –
1) Does the TT normally have a slot nozzle covering the width of
the runner bank or individual nozzles. Using 300psig with low
superheat gives a runner gap of about 0.01" so individual nozzles
would be mighty small.
2) Has anyone got formulas for calculating the parameters of
convergent (or convergent/divergent) nozzles to give a required
output velocity from a known feed pressure.

Any answers or pointers gratefully accepted

Richard Coleby

Richard,

    To the best of my knowledge only two nozzles are typically used in
a Tesla turbine, one for forward another for reverse. The width of
the nozzle is usually a little narrower than the whole pack. A single
nozzle for the whole pack is acceptable as the steam will flow pass
the disks and the close spacing of the disks soon makes it laminar
again. You may wish to recheck the disk pack spacing with Tesla's
widths which were larger than the 0.01 you are using. The narrow
spacing will not always give improved performance, but will greatly
decrease available power per disk. Pay attention to the spacing
around the end of the disks as leakage there is steam lost with no
work done.

   Hope this helps

Dave

Patent 5,782,414 gives a best fit curve calculation for supersonic nozzles.
The nozzle is broken into segments and each segment calculated based on
parameters such as nozzle diameter, pressure differential, etc.

I have low resolution gif images for the patents I can email you if you
want.

I plan on using multiple nozzles to begin with.  I see the disk edge as a
major producer of turbulance, causer of back pressure at the nozzle (no more
sonic flow), and an overall resistance to the desired power coupling.  In
the future I wanted to work with disk edge design to control flow insertion
between the disks without using multiple nozzles.

Using small nozzles means low flow volume with high velocity.  To get both
you have to use more nozzles.  Thats my intention.

My plan to make multiple nozzles:  small brass tubing from the hobby store.
I'll use a dull tubing cutter and roll the convergent section.  Then cut the
divergent section to the proper length.  I'll solder multiple tubes inside a
flatened copper tube (flattened oval).

I have this link to a micro supersonic nozzle test:
http://www.fmrl.fsu.edu/research/koustubh/koustubh/supersonic.htm

This link is a 1mm conv/div nozzle with supersonic flow:
http://www.fmrl.fsu.edu/research/koustubh/koustubh/fig3.jpg

I hope to have a real test soon.
