RH defines the limits of humidity. Greater than 100% and less than 0% are not possible so mapping the entire region between covers all possibilities. At 40*C (I am not sure what the temp was on the weekend), 25g/cu m (never heard SH expressed volumetrically before) is only about 65% RH so would certainly be anticipated as possible in coastal, tropical conditions.
Ingesting liquid water droplets is another matter - within limits this is usually beneficial.
From my limited info supersaturated is far higher meaning that AH can be higher than 100% RH, you might be able to see that on the Mollier curve. The 25 grams was an arbitrary figure for the discussion , it could be in reality much more.
Without getting into a merry go round I stick with my opinion until another feasible scenario comes along. Any thoughts on the pressure effect on that property would be welcome.
As I said before the effect of AH on these lambdas could be detrimental, it is area that those on the outside dont know about so I am just hypothesising.
I say that because propagation in a high lambda under what is probably SACI would be reasonably susceptible to interference.
The fact they have achieved such low combustion variability under high lambda conditions is a credit to them.
Horner said it was humidity and I took it as inferring the ICE.
Water droplets dont come into it because of the filtration and compressor effect.
I know you are alluding to the water/ methanol effect in aircraft engines but this is very different.
