New Flow Calorimeter for Multi-Wire Test

am .

We're happy to announce that we have a new tool in our quest for making precise, economical, and understandable experiments. HUG has engineered up a water flow calorimeter intended to be used with the small, LENR-stick type test cells. We will use this new calorimeter when we load many types of celani waire into one test cell in the coming days and weeks.

The calorimeter is detailed here: Water Flow Calorimeter Description  (Entire document embedded below, also)

The next step is for us to perform a careful calibration of the instrument with the empty Multi-Wire LENR-Stick.  This should be accomplished with the week.  

The data for this apparatus is not streaming, yet, but will be after calibration.  If anyone has a reliable, relatively new laptop that they would like to donate, we could use one that we could assign exclusively to this apparatus.

@HUG team.. you guys are really getting good at this! Keep up the excellent work.

PS - I love the "In God We Trust" firmly embedded into the manufacture of this fixture! : )


@Al, it's great to see your interest expressed and as always, your input in valued by everyone.

@Anton Perichta: the "stick" is a long and thin steel tube containing the active material. The stick is located inside a larger copper tube. The copper tube is heated by the stick by thermal convection (and radiation) and never exceeds 100°C. This is how this calorimeter can work without turning water to steam.

Can you please describe more in details the LENR- Stick construction? The stick looks like made in metal. When heeted to 500C it might be a problem to cool it down to 60C with water flow of 15mL/min and temperature 21.5C . Thank you for explanation.

It's a small point but I suggest that you not use an *empty* cell to calibrate. Instead, use one with inert wires, for example copper or stainless steel. And be sure to put in hydrogen at the same pressure as the experimental cell will run.

Other than that, great idea! Best of luck.

Partially related with the next MFMP experiments, might be an implementable idea for the next test runs:

iccf18.research.missouri.edu/. ../...

It appears that George Miley uses 60-100 psi (4.1-6.8 bar) in his Ni-H cells and, reading along the lines, that it is a necessary condition for excess heat to show. Celani uses relatively high pressures too, so I wonder if it shouldn't be better to stick with them rather keep using atmospheric pressures.

I like the concept of a standardized core module. I would like to see these more complex calorimeters be used to "certify" even simpler and more inexpensive apparatus that can be disseminated widely. One of my favorite candidates would be the conduction calorimeter. In this case the copper core tube would be wrapped in a thin insulating layer followed by an outer foil (or close fitting tube) layer. Ends would be insulated to force all heat to leave radially by conduction through the thin insulating layer. Heat flux is proportional to temperature difference across this layer. This is as simple as it gets. A slightly more complex arrangement would incorporate a null tube with a joule heater wire in it. The control circuitry could control to match the delta T's. Difference in input power = heat generated in active cell.

The water is nearly the only path for heat to leave the tube. With such heavy insulation, the heat has virtually nowhere else to go.
Errors caused by a change in temperature gradient around the tube circumference will be very small.
More important would be the errors caused by a change in temperature gradient along the length of the tube. That is minimised by having the water flow both directions along the length.

The major advantage to doing it this way is that with less length of tube the system is way more responsive because the water doesn't spend much time flowing through. It just goes up and back and carries the heat away. And that's the whole goal - to capture as much heat as possible from the device under test (without getting too warm and damaging the foam). Because of the thickness of the copper tube and the excellent thermal conductivity to the water from any point along the tube compared to the conductivity across the air gap to the LENR Stick test cell, I don't foresee strong temperature gradients around the copper tube and I don't expect we'll see more heat escaping from other paths. I could be wrong, but we'll see as we test it more.

What prevented you from using a coil tube heat exchanger like this?



With the current setup (tube running along a portion of the sides of the main 3/4" tube) if for some reason the heat flow inside the 3/4" tube changes once you install the multiwire LENR stick or swap it with something else, the initial calibration might end up not being valid anymore.




What you want is to exchange heat with as much 3/4" tube area as possible to avoid or at least greatly mitigate such potential problems.
