How the critical heat flux vary with channel size for the same mass flux? Is there a general definition such that CHF increases with channel size?

09 September 2018 1 8K Report

If we take same square channel of different sizes, and allowing same mass fluxes through both, the small one or the bigger one can withstand the early dry out. I conclude the bigger one since flow reversal is not that much intense...Is it correct?

Thank you Dibakar Pal

Got an explanation for this from the Review " Boiling and Evaporation in Small Diameter Channels", page 32 section "Critical Heat Flux".
