Lagrangian, mostly grid-free methods, offer natural approaches to simulate convection, adaptively, while avoiding diffusive errors. They have been extended successfully to finite Reynolds number flows, low Mach number combustion, and high Mach number flows. This presentation summarizes the essential elements of Lagrangian, grid-free methods, and demonstrates their applications in a number of nonreacting and reacting flows of canonical and practical interest.

Keywords:  Lagrangian methods; Vortex and particle methods; Smooth particle hydrodynamics; Fluid flow, Combustion
