The mathematical model of steady-state flow of incompressible and nonisothermal liquid rivulet moved by a gas in an inclined minichannel was developed. Action of van der Waals and capillary forces, as well as gravity and tangential stress at the gas-liquid interface are taking into account. Numerically it is found out that rivulet formation gives a significant disturbing effect on the gas velocity distribution. It is shown that at the rivulet profile clearly visible three-phase contact line and region with practically constant inclination could be seen near the thin liquid film areas. The angle of this inclination could be considered as a contact angle. Region with practically constant derivative of the function h(y) with respect to y, near the contact line confirms this statement.
