Our main focus right now should be to prevent

overall boiling while still experiencing localized nucleate boiling.

Russell and Paul,
An interesting fact established fairly long ago, the Chevy drag racers WANTED nucleate boiling around the exhaust ports! I
believe Bill Jenkins mentioned it in the excellent HP books "The Cheverolet Racing Engine." That book is 20 -30 years old now. I
would really like to know how they established this fact!
I really don't think ANY boiling would be good for the stability of the Rotary's combustion chamber. Bill Jepson

Nucleate boiling is the normal mode of heat transfer.
