hi
i founded tutori about 2D fluidized bed finally i can do a simulation, now i want to try to modelete a 3d fluidized bed i read a articl : Two-fluid modeling of three-dimensional
cylindrical gas–solid fluidized beds using the
kinetic theory of granular flow [ https://ufile.io/ea22 ( for download) or https://www.researchgate.net/publica...3D%3D&el=1_x_3 ]
the author used diffirent equation ( Continuity equation-Radial momentum.....) the author use cylindrical coordinate, for me i don't know if i must to write the new equation( cylidrical domaine) with UDF to use it for the simulation? if someone have i idea reply to me pleeeease
