Critical heat flux of saturated convective boiling on uniformly heated plates in a parallel flow

Employing saturated water and R-113 at atmospheric pressure, experiments are made for critical heat flux (CHF) on a uniformly heated plate of 10, 15 and 20 mm in length submerged parallel to a uniform liquid flow with velocity of 1.5–10 m/s and the data of CHF obtained are successfully correlated by a generalized equation. In addition, it is shown that existing data of CHF for acetone, toluene, monoisopropylbiphenyl and water flowing through internally heated annular channels of very small I/d_he, where I is the axial length and d_he the heated equivalent diameter, agree well with the above-mentioned correlation.
