A generalized graphical method for predicting chf in uniformly heated vertical tubes

Abstract A general correlation is presented for calculating CHF in vertical tubes during subcooled and saturated boiling. The correlation has been compared to 1271 data points from more than 30 sources and found to hav a mean deviation of 15%, with 90% of data within ±30%. Data include water, potassium, freons, benzene, ammonia, parahydrogen, and nitrogen. Reduced pressure range is 0.0012 to 0.94, mass flux from 6 to 24300kg/m2 s, critical quality from −2.6 to +0.96, and inlet quality from −3.0 to positive values ∗
