Could someone help with explaining the DPM sample report (for one trajectory) show below:
( x y z u v w diameter t mass-flow mass frequency time name)
((-2.1816e-01 -1.3009e-01 5.5559e+01 -7.1835e+01 -4.2239e+01 -4.3358e-01 1.8500e-04 3.0000e+02 4.5504e-03 8.7854e-09 5.1795e+05 7.6812e+00) injection-0:861)
I'm injecting the particles through a surface and I'm using a stochastic tracking with 20 tries.
the diameter of each particle I'm specifying is 1.8500e-04 m. What is the t value of 300 ?
The mass flow of 4.5504e-03 is the mass (8.7854e-09) times the frequency (5.1795e+05). Does that mean every parcel is made of 5.1795e+05 particles ?
If that is true, does fluent do the force balance, when a DPM iteration is done, on the whole parcel that is made the 5.1795e+05 particles with the total equivalent diameter or it uses the diameter of one particle only ?
