THIN LIQUID FILM PROFILE NEAR THE INTERLINE REGION IN A CAPILLARY TUBE

摘要：

Thin liquid film profile is important for heat transfer in microscale space. The asymptotic analytical solutions for thin liquid film profile in a capillary tube are obtained by the perturbation method. The variation of the film thickness, the contact angle of the vapor-liquid interface and its axial curvature depend on the effects of the disjoinng pressure and the capillary pressure. The thin liquid film profile will change significantly near the interline region. The obtained solutions are convenient and applicable for problems of thin liquid film in a capillary tube.
