The paper acquires the images of triple phase contact line along the axial direction in microgroove triangle wetting region by the direct visualization means. The contact line images are processed by computer software, and the change law for triple phase contact line is obtained. The contact line angle between contact line and axial direction along microgroove is obtained by analyzing contact line. Results indicate that the length of contact line and the thickness of liquid film on side wall of microgroove reduce along with heat flux addition; but increase as the tilt angle increases. The contact line angle increases with the increase of tilt angle and the decrease of heat flux. In addition, changes of the length of contact line, the thickness of liquid film and the contact line angle for ethanol case is more significant than that for distilled water.
