A study of the dryout characteristics in forced convection boiling in electrically heated horizontal helically coiled tube is reported. The results demonstrate that dryout usually occurs at the front (θ= 90°)and back side (θ= 270°) of the exit cross - section. The secondary flow induced by centrifugal force and the wall heat conduction around the dryout points are the dominant mechanisms of dryout in a helically coiled tube. Based on the experimental data
a correlation for predicting the critical dryout quality of horizontal helically coiled tube is proposed.
