Abstract: pu te the temperatu re field of the tube w all, a one dimen sional m athem atical model
has been bu ilt in th is paper. T he temperatu re field of tube w all under the condition of un ifo rm heat
flux and field of heat flux under the condition of the sam e w all temperatu re have been calcu lated
respectively. M oerover, evapo ration length s of w ater drop let under differen t condition s are ob tained.
T pu ted resu lts are in good agreem en t w ith the experimen tal data and can be u sed fo r
engineering p ractice. F igs 7 and refs 3.
Theme words: w et steam ; w ater drop lets; heating
