Duplicating published results many a time is very challenge, as you may not get exactly the same parameters, including the device material, simulation settings. Please refer https://forum.ansys.com/forums/topic/ansys-insight-why-my-simulation-result-is-different-from-published-paper-or-experiment/

Suggestions:
please use overrid finer mesh for the particle region, and the coupling region. Make sure the material is correct and simulation time is long enough with smaller than autoshutoff min.
