Computational study of thermocapdulary convection tn a float-zone
Abstract
Development of a new computational tool for the study of thermocapillary convection is presented. Details of the mathematical model are followed by a description of its computational implementation. The resulting computational model is time-accurate and permits the free surface to deform rather than requiring á priori specification of the interface shape. Fidelity of the new model is demonstrated by reference to published experimental, analytical, and computational data for thermocapillary flow in a cavity and a float zone. The model is then used to study the influence of Marangoni number and gravity level on thermocapillary flow in a float zone. Steady-state temperature and velocity fields are presented. Selected sequences of fields from the transient calculations that expose the influence of gravity level on the evolution of thermocapillary flow are also presented.
