I use the particle with FLOW-3D v9.4.
In the text output, I choose the particles this option.
And then I can see the data, however,
I don't understand what is mean about xp,yp,zp,vp,up,wp, and psiz.
Do the xp,yp,and zp are mean loction?
Do the vp,up,and wp are mean velocity?
By the way, does the drift-flux model use the fully Navier-Stoke equation?
xp, yp and zp are particle instantaneous coordinates, and up, vp, wp are the velocity components, psiz is either particle size or density, depending on the option chosen during setup.
The drift-flux model uses the full Navier-Stokes for the mixture and a reduced, drift-flux approximation for the relative motion, where inertial terms are neglected.
