Introduction: "Experiments on cold nuclear fusion and LENR"
At the time 00:00:54 (hh:mm:ss) the switch that allows electrical power to reach the setup has been activated and the supply of current has started. At 04:11:44 the same switch was turned off and the power supply was cut off. The supply voltage was kept constant for the entire duration of the test while the current is free to vary (driving in voltage limitation). The graphs show that the current and consequently the electrical power increase in the first two minutes of delivery and then remain constant at the maximum value (apart from an oscillation in the reading of 0.1A which is the sensitivity of the instrument).
The following graph shows the trend of the temperature difference (DT) and of the water temperature before entering the exchanger (Tin).
Before starting to supply electrical power, DT is zero or equal to the sensitivity of the measuring instrument (±0.1°C). Compared to the activation of the switch that starts the delivery of electrical power, the DT begins to increase with a certain delay due to the thermal inertia of the heat exchanger. The DT value stabilizes within a few minutes and its variations subsequent to the initial growth are believed to be attributed to mixing of the water inside the heat exchanger. At the end of the electrical power supply, the same delay in the response of the DT is observed, always induced by the thermal inertia of the heat exchanger.
The measurement of the flow rate of water was carried out at the beginning and at the end of the test. Assuming that the variation of the water flow is linearly dependent on the elapsed time, the trend shown in the graph below is obtained.
By adopting the flux value shown in the graph, the trend of the generated thermal power (Wt) and also the trend of the instantaneous COP as the ratio between the thermal power output and the electrical power input (COP=Wt/We) are calculated. Since it is not possible to calculate the COP value when the electrical power input is zero, in the absence of electrical power it has been chosen to reset the COP value.
Integrating the thermal power output and the electrical power input over time, exchanged energies are determined and the following graph has been obtained from their ratio.

NOTES ON THE EXPERIMENT
The reported experiment is the second of a series of tests aimed at characterizing the reaction chamber response to varying conditions. Compared to the previous experiment (Experiment of March 12, 2021) the power supply voltage was increased and in this way the electrical power input increased.STIMULATION TYPE
