The recombination is exothermic, certainly, but the dissociation, it consumes energy (thermal?) I suppose?
Even if the primitive heating by the reactor and the electrification which can act like a catalyst (lowering of the energy level to reach for the reaction to start) facilitates the thing, there is inevitably a loss somewhere, it seems to me ?
Hello !
Good question, I had already asked ...
Yes, the dissociation is andothermal (it eats calories), but we must not forget that, in the case of an engine, what interests us is the useful mechanical energy that is recovered from the pressure of the combustion gas.
The flame, we do not care, the flame, it must cool, since the heat it releases borders the 70% of the overall energy generated.
This means for example, if we do the calculations "with a ladle", that for an engine of 50 hp (useful power), whose efficiency is 30%, we have:
Pmot = 50cv X 736 W = 36800 W, ie 36,8 KW
Pmot = 30% of Ptot (total power)
therefore, Ptot = 36,8 * 100 / 30 = 122 KW
We deduce the energy dissipated in the form of heat, Pc:
Ptot-Pmot = Pc, here about 86 KW ...
This is the "lost" energy, the one from which we try to extract something with the pantone (among others).
It should not be forgotten either that Pt is the nominal energy of the mill, but that for a car, the engine is rarely solicited in its maxima, and tends to work under load ... let's say 20% ... it still leaves about 17 KW to dissipate (the equivalent of 8 electric radiators of 2000W ...)
This heat is evacuated by the cooling system (air, water, oil), and residual, in the exhaust line, and ultimately in the air, because the GE are hot ...
The fact that the cracking is andothermal is not a problem in that we have a huge energy field, in which we can shamelessly tap to light our watery firecracker ...
... after the end, it will be a little less calories to be evacuated by our cooling system, (we must try to draw maximum
Let us not forget either that the exothermic reaction which follows the dissociation will itself restore part of the energy that it had previously "pumped" (T ° combustion of hydrogen, 2300 ° C).
)
Of course, we have to find the right ratios between the size of the H2O molecule cluster, the total amount of electrified vapor swallowed in the intake, and the amount of fuel that will be burned - necessary
and sufficient - we will try to reduce as much as possible.
All is about limit, find the right settings, it's all about measures and manip to mount.
We're working on it, going home, we're getting a BE, with a test bench, it's going to be serious
It remains to find the corner where to put the gear (yanaplein !!!
)
A + + +
We were on the brink, but we made a big step forward ...
