A new model which well explains the stochastic characteristics of the dryout phenomenon observed on evaporating tubes is proposed. In this model, the dryout region is intermittently quenched by liquid fed by the disturbance waves arrived at this region and suffers rather random wet-dry cycle, which causes the wall temperature fluctuations. In order to prove validity and usefulness of this model, a Monte Carlo simulation study is conducted at the condition corresponding to a typical run of our experimental data reported in our previous paper. The power spectra of the wall temperature fluctuations are well approximated by our model, which shows its superiority to the rivulet model. Some properties of our simulation model are also examined.
