Eulerian vs lagrangian approach
WebLagrangian mechanics are better when there are lots of constraints. The more the constraints, the simpler the Lagrangian equations, but the more complex the Newtonian become. Lagrangian mechanics is not very suited for non-ideal or non-holonomic systems, such as systems with friction. Lagrangian mechanics is also much more extensible. WebCurrently there are two approaches for the numerical calculation of multiphase flows: the Euler-Lagrange approach (discussed in Section 15.1) and the Euler-Euler approach (discussed in the following section). The Euler-Euler Approach In the Euler-Euler approach, the different phases are treated mathematically as interpenetrating continua.
