Title: Flow and yield surface characterization of generalized Bingham fluids in complex geometries
Abstract: This project investigates the flow behavior and yield surface evolution of generalized Bingham fluids within complex geometries, including circular pipes with contractions and channels featuring sudden expansions. By integrating analytical approximations with numerical simulations, the study aims to characterize how key rheological parameters such as yield stress, consistency index, and flow index, affect the formation and extent of plug regions, velocity profiles, and overall flow patterns. Emphasis is placed on identifying critical transitions in flow regimes and understanding the interplay between geometry and non-Newtonian fluid properties.
Prerequisites:
· Fundamental knowledge of fluid mechanics,
· Familiarity with rheological models (e.g., Bingham, Herschel–Bulkley),
· Competence in calculus and differential equations,
· Experience with numerical methods (e.g., finite difference or finite element methods),
· Basic programming skills.
