Eularian and Lagrangian approachesEularian and Lagrangian approaches seem to be the two methods to study fluid motion. The Eularian approach concentrates on fluid properties at a point P (x,y,z,t). Thus it is a field approach. In the Lagrangian approach one identifies a particle or a group of particles and follows them with time. This is bound to be a cumbersome method. But there may be situations where it is unavoidable. One such is the two phase flow involving particles.
