thank you bageshwar, i've solved my problem.
it was that a cylindrical/conical based cylindrical spouted bed should not be simulated by a 2d-plan model , it should be simulated by a 2-d axial asymmetric model , assuring that the inlet velocity and the superficial gas velocity are in accordance with the experiment results.
