Thanks Gigi, I am continuing to develop the model further and as I give it consideration I find that it may allow us to obtain a second, accurate backup calculation for Jed's original conclusions. We appear to be able to enter known data, including the 20 watt drive pulse and the pump leakage power along with ambient temperature conditions into the model and obtain a well defined temperature versus time plot.
Your original model does a remarkable job of replicating the measured results from the point in time where it begins to model the linear system. Now, I have figured a way to extend that initial time as far into the past as needed in order to determine the magnitude of the LENR power pulse. To achieve that goal it is necessary to have reasonably accurate measurement data for the ambient temperatures over that entire time period. I believe that Jed has that information available within his files. Jed, can you verify that this is true? According to the excellent work by Gigi, we have a model with a main basic time constant of 5.84 hours. This is the dominate pole of the system and therefore we will need to operate back in time with the input data for a period at least 3 time constants in order to obtain an accurate projection of the thermal behavior of the Mizuno device. The really good news is that we should be able to begin our analysis at the beginning of a day just before the power pulses are applied and make a decision at the end of that same day (24 hours) with reasonable accuracy. At each increment of time we will need the value of the ambient temperature and any applied power plus the assumed magnitude of the resulting response power of the LENR process. We can include the 4 watts of leakage for the pump which Gigi has determined as just another input that is constant over the simulation period. If the model works as it should then we will see good agreement between the water temperature over that entire time period and what the model predicts. Obviously we will need to have accurate data of the initial conditions of the system, which in this case is the water temperature just prior to the first power pulse, in order to begin the simulation.

We are still thinking about the problem of not uniform temperature across the reactor vessel just after the power pulse are applied, but it seems to me that you have solved them. I hope to read the full report very soon. GG 2015-01-16 5:29 GMT+01:00 David Roberson <dlrober...@aol.com>: I ran out of patience waiting for an input from Gigi and decided to construct a simple numerical model of the calorimeter used with the Mizuno test. After playing around with it for a while using the thermal values derived by Gigi and his team, I have come to my first conclusion. It is a bit early and I might find a glaring error somewhere with further analysis but felt it was reasonable to offer an interim report. It is consistent with the model for the device to be generating an output power of 100 watts. I have rounded the value off at this time until further research can pin point it more accurately. Even if 4 watts of leakage is present due to the pump action, the calorimeter appears to be fairly immune to that input provided the ambient does not change more than 2 degrees during the test. Again, this is a first pass result and subject to revision. Dave
