Isogeometric analysis of droplet deformation in shear flow

The Boundary Integral Method (BIM) is applied to investigate the dynamics of a single drop in isoviscous shear flow. The novelty of this work compared to the previous studies in this field is the application of Isogeometric Analysis (IGA) to define the interface of the drop. Singularity subtraction is applied for efficient numerical integration. Excellent agreement between the current results and the traditional BIM is observed. The approximation properties of the spline representation of the drop interface are studied both for the initial configuration and for the motion of the interface
