Laminar boundary-layer flows of gas and liquid having a phase-changing interface at their common boundary are studied theoretically to predict their aspect of flow and thermal fields first in the steady state. By using these results and examining their perturbed fields with small wavy disturbance, the disturbance flow fields and the hydrodynamic instability of the system are investigated. The phase-change at the interface has a considerable effect on the velocity and temperature profiles, thus on the coefficients of skin-friction and heat-transfer at the interface. Intense evaporation decreases the velocity and temperature gradients at the interface. The wavy disturbances on the interface have influence on the heat-transfer at the interface by one order of magnitude less than on the skin-friction. The small wavy disturbance fields show a hydrodynamic instability similar to that of boundary-layer flows on a rigid wall.
