experimentally investigate the migration of liquid
bridges at the interface of spheres and plates with an imposed thermal
gradient. The key influencing factors of interface gap, sphere material
and diameter, liquid viscosity, and thermal gradient on the migration
behaviors are highlighted. Furthermore, the physical mechanism of
this intriguing interfacial phenomenon is numerically unraveled. The
originality of this work lies in the fact that when thermal gradients
were encountered, liquid bridges could migrate at the interface of
spheres and plates, and a general design philosophy of related parameters
for enhancing or weakening this thermal flow is proposed.
