A numerical model is developed to investigate the velocity fields of high prandtl number liquid bridge with surface deformation under microgravity. The Navier-Stokes equations coupled with the energy conservation equation are solved on a staggered grid. In the numerical calculations, the free surface deformation and the effects of ambient air are considered. The surface deformation of liquid bridge is captured by using level set method of mass conservation. Results of lateral and axial velocities on different radius are given. The lateral and axial velocities near the free surface are larger than that near the center of liquid bridge. The lateral velocity and axial velocities on the interface tend to be uniform with the development of thermocapillary convection.
