Default Pressure drop vs velocity curve in Fluidized Beds

Hi everyone,

I am working on my thesis and for that reason I need to replicate my experimental setup in CFD. Basically, my model is very basic. it is just a rectangular 2D model in which I am providing velocity at inlet and calculating pressure drop across the fluidized bed. In simple words, I aim to obtain the characteristics curve of fluidized beds. (The pressure drop increases linearly with increased velocity up to a limit called as minimum fluidization velocity and then the pressure drop remain constant.) I am new to CFD and all, no matter how much I increase the velocity the pressure drop is not becoming constant at all. I have tried different models and even tried replicating models of some existing published articles, but not success so far. I really need assistance. Can anyone here please help me with this to get a characteristic curve. I am struggling since past 3 weeks.
