Multiphase particle-in-cell method

<p>The multiphase particle-in-cell method (MP-PIC) is a numerical method for modeling particle-fluid and particle-particle interactions in a <a href="/facts/Computational_fluid_dynamics/zuWdtNJp">computational fluid dynamics</a> (CFD) calculation.  The MP-PIC method achieves greater stability than its <a href="/facts/Particle-in-cell/EF4cFzg0">particle-in-cell</a> predecessor by simultaneously treating the solid particles as computational particles and as a continuum.  In the MP-PIC approach, the particle properties are mapped from the <a href="/facts/Lagrangian_coordinates/sYLvgboC">Lagrangian coordinates</a> to an <a href="/facts/Continuum_mechanics/vI7LpFDk">Eulerian</a> grid through the use of interpolation functions.  After evaluation of the continuum derivative terms, the particle properties are mapped back to the individual particles.  This method has proven to be stable in dense particle flows, computationally efficient, and physically accurate.  This has  allowed the MP-PIC method to be used as particle-flow solver for the simulation of industrial-scale chemical processes involving particle-fluid flows.
