This book investigates the complex behavior of two-phase flows when the solid phase is composed of particles of varying sizes. It delves into the critical regimes where the flow transitions between different states, examining how the distribution of particle sizes influences these transitions. The work is grounded in fluid dynamics and aims to provide a deeper understanding of these phenomena for researchers and engineers.

The book is a technical monograph aimed at specialists in fluid dynamics and chemical engineering. Its focus on the specific challenge of polydispersity in solid phases suggests it will be of interest to researchers working on complex multiphase systems. The detailed analysis of critical regimes indicates a rigorous, data-driven approach that is likely to be valued by the academic community.
