A fresh look at the Clem motor

[mäxchen]

I've sat on the sidelines on this one for years.
I apologize for never taking a look at it....


Horsch (did i spell that right)
Vortex Tube thermal seperator


So try to follow along:


The rotating vortex of air seperates hot and cold air from the ambient
the hot air is jetted out of the nozzles, the force of which is pressure dependent:
Pressure is temperature dependent.....


Therefore, increases in temperature of the output air increases the rotation of the vortex


There seems to actually be a temperature where this force exceeds the driving force required for the vortex tube to function.


This machine may check out, don't give up


Hope this helps. Life is happening again, so i wont be building for a few months, but i am rather interested in this one now, so its on my list.

Are you talking about the Matzenauer Rotor?

No thats my analysis of the actual clem motor.
Based on the available information.


Take it or leave it

The most important factor to recognise is that the fluid comes out of the nozzles at drematically reduced pressure and temperature. A stumblimg block for the expectations others hold to.

The math says there is both cold and hot vortices.
I would expect heat to transfer to the rotor, as it is the thermal expansion that drives its rotation.


This is not the same situation as something by like Heron's steam engine, devices like that operate only on changes in pressure like any other steam engine.


Clem is using a different process. One of thermal separation from the ambient. This is a fuelless process, and as long as the vortex remains coherent, it is renewable.

I found the reference: Hilsch was the name
https://en.m.wikipedia.org/wiki/Vortex_tube


The math truncates at low velocities, however the effect does not cease. It still occurs at low rotational speeds, however to a much lesser degree.


The small pressure from the cooking oil begins the rotation and slightly warms the intake air
(this is mostly nitrogen w a little CO2, as the oxygen has been combusted at this point.)
The inner vortex splits this into 2 interlaced streams
(both ends of the vortex tube are the same end in this setup)
the difference in temperature causes a difference in pressure, which exerts a force in the direction of rotation as the hot air expands and cools.
There should be a detectable temperature difference between the center and the outer of the exhaust stream.

Using vortex math we can then calculate the average temperature drop from 300 to the output temp and get a feel for the work done by the engine.


Look at the Dirac centrifuge, very similar process,
