This presentation explores the flow rate properties of deformable  particles in confined geometries, with a particular emphasis on active  deformation and its effects on mobility. Using minimal models of  self-propelled particles, we simulate their behavior in various  configurations, such as flow through constrictions and in crowded  environments. By introducing active deformation, where particles  change their size or shape over time, we demonstrate how these  dynamics can optimize flow rates and prevent jamming at high  densities. The results reveal an optimal frequency of deformation that  enhances particle throughput, providing insights into the fundamental  principles of efficient transport in complex systems.
