The Lagrangian‐based framework for mixing time distribution (MTD) was established by discrete phase model (DPM) trajectories extracted from previously validated computational fluid dynamics (CFD) simulations and applied to the steady‐state Reynolds‐averaged turbulent flows in T‐shaped microreactors. For each tracked fluid element, the individual mixing time was defined as the duration from its concentration beginning to change to reaching a specified tolerance band around the uniform state after completely mixing. The MTD functions and spatial mapping of individual mixing times to injection locations were analyzed to reveal the flow path diversity of fluid elements, and the average mixing time results showed excellent agreement with reference methods.
