Abstract
A parametric experiment of saturated pool boiling on a horizontal heated wire was performed, by changing parameters such as test liquid, wire material and system pressure, to make clear the dependence of critical heat flux on wire diameter. Over 1000 data are accumulated for the slender wire with various diameter and correlated in dimensionless form like Sun-Lienhard' s. It is found that the CHF data scatter is very large even if the test condition is kept to be the same. In the present report, the reasons of the data scatter is experimentally studied and discussed.
