The curve I was referring to is the T2(mis) curve. There is a well defined bump that peaks at 16:00 time. This is one of the curves of the actual ECAT measurement and I was looking to see if your source demonstrated anything resembling it. I was expecting to see a reason that the model did not predict the relatively short duration "bump" that is so evident. Unless I am wrong, I interpret his explanation as "not really knowing" since this is the region where the most temperature delta occurs between his model and the real world. That is an OK answer for him to have-his model does not include the possibility that the LENR reaction produces a large pulse at this time due to the drive waveform that I described in my analysis explaining this bump. Also, the output power measurement at the same time shows a COP of 3 matching the input power pulse. We may have found additional proof that LENR is occurring which a non LENR model can not explain.

It looks like this is not demonstrated in any of his curves. The bump is in the temperature of the ECAT water bath T2 and is very distinct. Here is the reply: "If you are referring to the green curve T_2w, it is not a bump, it is a sharp angle. It appears when the water temperature reaches the boiling point correspondent to the pressure inside the ecat. From that point on, the water temperature no longer rises due to evaporation. That pressure includes an over pressure due to the relief valve, which has been supposed to be 0.8 bar. That's the point where the T_2w deviates more from the measured value T2(mis), for the rest of the time difference is less than 5°C. Also, consider that the thermocouple was placed between the fins of the heat exchanger and remains above the water for the first part of the transient. In addition, the internal pressure in the ecat, and hence the temperature, can change depending on the steam/water outflow. These phenomena are not included in the model."
