TīmeklisDr. Reetesh Ranjan. Assistant Professor, Mechanical Engineering. Abstract: The proposed research focuses on further enhancements in the Eulerian-Lagrangian (EL) formulation for large-eddy simulation (LES) of turbulent dispersed multiphase flows.Such flows are observed in several engineering applications and natural systems, and are … TīmeklisA Lagrangian analysis of fluid kinematics establishes a fundamental connection with the Eulerian stress field in viscoelastic flows. These results provide a framework to determine the stress topology directly from conventional experimental flow measurements for arbitrary viscoelastic fluids and flows, including 3D geometries …
