摘要：

The quasistatic thermocapillary migration of a liquid drop normal to a plane rigid or a free liquid surface is analyzed using bispherical coordinates. Results for the ratio of the drop speed in the vicinity of the surface to the speed when isolated are calculated and presented for both rigid and free surfaces. The results illustrate that drops of sufficiently high thermal conductivity compared to that of the continuous phase can move more rapidly in the presence of a free surface than when isolated. An explanation of this surprising observation is given. Also, representative streamlines which exhibit interesting flow patterns are presented and discussed. © 1990.
