Quick Summary

In physics, transport phenomena describe the movement of entities like mass, momentum, or energy through a medium due to non-uniform conditions. When variations in concentration exist within a medium, it leads to the relative motion of chemical species, a process known as diffusion. This mass transport is a fundamental aspect of how substances move and interact within physical systems. Diffusion is crucial in various processes, including combustion, where it facilitates the interdiffusion of chemical species.12
