Re: EXTERNAL: Re: [Vo]:Questions Raised by Parkhomov Experiment Failure
To improve the internal heat transfer look for an inert gas--He for example.
He is a good and rapid heat transfer agent and would act to maintain a more
even temperature within the reactor. It could even improve the alumina itself
if sufficient porosity is incorporated into its structure. Also an inner
cooling/heating tube might be desirable to better control the reactor
temperature.

Bob, very nice design [I downloaded from home] and realized the gas/plasma
inside the tube is a far superior transfer medium. I understand your purpose of
only transferring heat in case of temp increase when the drive is removed for
calorimetry BUT would you also consider dual use as part of the control loop
instead of just for calorimetry.. this would be an additional [luxury] test
where instead of only on to dampen temperature rise it is always on at mid
speed requiring much more heat from your drives to reach threshold. This would
be the “isometric” situation I mentioned where the cooling fan is fighting the
work of the drivers. IMHO this environment would be more robust at exhibiting
the anomaly if it is present because you have dual controls allowing the drives
to be reduced more as the load is modulated instead to keep the device at the
same duty factor of runaway before being pulled back by increased air flow
[push pull of air flow above and below an average level instead of just on
off].. if nothing else it may provide finer control of the system via
combinations of drive pw and dynamic cooling.

Yes, this is why I was worried about Alexander's new design that puts an air
gap and another ceramic around the reactor core - increasing its thermal
resistance to the lower temperature air around it and/or the water in the
calorimeter. He already showed that if he put alumina powder insulating the
reactor (to lower the input power to get it high temp) that it failed
catastrophically.
I am working on a large water volume calorimeter in which to test my
Parkhomov-like reactors. It will include a variable convection fan to change
the thermal resistance between the reactor tube and the cool water in the
surrounds. This convection will only be activated if the heater coil power is
turned off and the temperature of the reactor continues to rise. The intent in
this design is for the water to never reach boiling. Also, the calorimeter
will be a good shield for any explosive shrapnel (primarily alumina shards).
The calorimeter also provides a port to measure radiations with low mass
density between the reactor core and the sensor. Here are 2 links to diagrams
of the calorimeter I am building:

Here is the link to my planned ZDV plumbing that will allow me to measure the
pressure, sample the gas product, and vent the system before opening the
reactor post-experiment.

As Bob Greenyer likes to do, he has dubbed this system in ASCII as {Garbage
Can}.

Re: EXTERNAL: Re: [Vo]:Questions Raised by Parkhomov Experiment Failure
Thanks Fran. I would love to be able to just see the XH to start. It would be a happy circumstance to then go on to evolve the software control to regulate temperature by modulating the thermal load. I am most of the way through making the small pieces for the convection system (it will have 4 ball bearing mounts). All of this needs to be capable of working at fairly high air temperature (but the drive motor will be outside the box at ambient temperature). In the DAQ that I use (Omega DAQ-56), I have 4 counter inputs. I am using 2 of these for radiation counts, and I could use one for tachometer pulse counting from the fan drive shaft. Then I could use 4 of the digital outputs of the DAQ to provide fan motor speed control - so it wouldn't have to be 1 bit on/off.
