摘要：
Direct Numerical Simulations (DNS) based on the Volume of Fluid (VOF) method are carried out in this work, with the aim of analyzing the primary breakup of an inelastic non-Newtonian jet. Detailed description of the jet phenomena is provided firstly, followed by analysis on the generation of ligaments and droplets. The non-Newtonian characteristics of the jet are discussed as well, with a modified Ostwald de Waele model applied for the computation of the shear thinning liquid viscosity. Further, information about the current status of the MPI optimization regarding the Cray XE6 platform is revealed and a first performance analysis is presented.
