Multicomponent Conservation Equations

There are two fundamentally different ways to describe the motion of a fluid: Lagrangian or Eulerian. From the Lagrangian point of view, the flow field is regarded as the motion of numerous small, contiguous fluid elements which interact through pressure and viscous forces. The motion of each fluid element behaves according to Newton’s second law of motion. Though appealing to the student of Newtonian mechanics, this approach is generally impractical to describe the flow of a continuum because of the large number of mass elements needed to achieve a reasonably accurate description of the flow field. On the other hand, the Lagrangian approach is worthy of consideration for dispersed two-phase flows (gas-particle, gas-droplet) in that the particles or droplets themselves naturally constitute individual mass elements.
