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?

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...
