Water spray to steam during compression in a hybrid diesel-steam engine

[pranj5]

I just have read about a new kind hybrid diesel-steam engine where water has been injected inside an internal combustion engine to improve efficiency. The basic principle behind the process is that water will soak up a large section of heat generated by burning the fuel and will turn into steam that will improve the efficiency of conversion of heat into power. While reading a thought suddenly stuck my mind. If atomised water is injected to steam during compression inside a steam compressor, what can possibly be happen. It can certainly be said that the water will soak up the extra heat generated during the compression and will keep the steam saturated until all the water will be converted into steam. I just want to know how much right I am.

The water will soak up some of the heat generated during the compression. The steam will soak up some as well.

...and will keep the steam saturated until all the water will be converted into steam.

That isn't intuitively obvious to me and I expect is wrong. But isn't this the same claim you've been making over and over again here? Weren't you already shown how to do the analysis to find out what actually happens? Why don't you just do the analyisis, post it and we'll help make sure it is correct?

I have already posted my analysis here in this post. I don't want to post the mathematical details here. I just want to see that whether others agree with what I have thought or not. This thread is different from before by one aspect. In the previous, the whole attention was concentrated on mechanical work. In this thread, I just want to see whether the mechanical work can be replaced by heat or not. In the formula, what has been stated is just the change in enthalpy and that can be done by both mechanical work and adding heat. If the same effect can be achieved by just adding heat, that means a huge leap forward.

We have been through this before: "analysis" means math. Anything else is just handwaving, and we do not allow it. Since you have stated that intent, this thread will not be useful and is therefore locked.
