So you agree that metal atom in a fuel CAN be excited to emit photons? Isn't this what you have been against? Isn't it your whole point that color from the a flame comes from hydrocarbon burning, but not from metal atoms being excited? Now you are shouting out that metal atoms can be excited!

I never said that metal atoms cannot be excited , I said there aren't enough of them to change color of the flame ! .

And I have NEVER mentioned anything about electrons absorbing energy from kinetic contact. Kinetic energy has absolutely nothing to do with exciting valence electrons in a way we have been talking about.

Well , if they do not absorb it from kinetic contact , they must absorb it from radiation . And where that radiation comes from ? From oxidation (burning) of fuel .


vesicles said:
And by suggesting thermal radiation is the main way of heat conducting in an AB, are you saying that most of energy from the burning of fuels in the AB has been released in the form of thermal radiation?

No , most of the heat (i.e. energy) is retained as kinetic energy of molecules . Gas cools down (on macroscopic level) by mixing with cold air outside of the engine (diffusion of gas ) . What energy is lost , is lost in form of radiation .

Uh.. atomic bomb does not generate energy by itself. Nothing does. Ever heard of conservation of energy? Nothing can generate energy... It has to come from somewhere, even for atomic bombs. You still need an energy input.

Yes it does . Internal energy (nuclear energy) is released outside . Law of conservation of energy is not violated . In case of excitation of electrons , energy comes outside and it is released outside . Atomic bomb does not depend on other systems , excitation of electrons does ;)

Btw , further discussion is pointless , I quit .

Yeah, I feel the same. It's like all I have said have fallen into deaf ears. I have painstakingly described how electrons can be excited and what the sources of excitation can/cannot be, but it sounds to me that you have read/understood none of it. Talking about depressing...

BTW, nuclear fission requires energy input, like anything else that goes on in this universe. Not only that, it requires HUGE amount of energy input to initiate. How huge? For heavy nucleus, like U-238, the energy input would be ~ 7-8 million electron volts...

I apologize for keeping going at this. But I feel that I need to address some of the glaring mistakes so that visitors to this forums would not have a wrong impression of our forum. This is the end of this discussion.

We've all been there before, I suspect. Comes with the job, so to speak.

Well, to get thread back on topic, how about some news about WS-15? and what about WS-13?

i think its been 3 years since we last heard about WS-15.

Sorry. Nope. The day we get some news on those is the day this thread grows 5-10 pages in an instant.

The WS-15 is doing some high altitude testing I think (no official confirmation).

Devil if I know what the WS-13 is doing.

That's a few yrs ago already. WS13 taxi run and again that's couple yrs ago and disappeared. Insiders said CHina will continue to need to import Russian engines at least til 2020. More than ws10A, the overall status of all China engine development is slow and unclear.
