Vl. Malyshev, Nonisothermal effects of vaporization under conditions of superheating of liquids in capillaries above the boiling point, HIGH TEMP, 36(6), 1998, pp. 915-919
A slower-than-theoretically-predicted rise of the rate of evaporation of li
quid from capillaries with the intensification of the process is attributed
to the effect of self-cooling of the surface of phase transition. The theo
ry of this phenomenon is suggested. The transition (between Stefan and visc
ous) mode of evaporation in the presence of longitudinal temperature gradie
nt is treated. The equation is derived for the dependence of excess pressur
e on temperature and channel radius. Expressions are found for the vapor fl
ow, for the rate of interface shift, and for the time of evaporation. Compa
rison is made with the experimental data.
