Throttling Process of Rotating Bardeen AdS Black Holes

In this paper, the author study the throttling process of the Rotating Bardeen-AdS black hole in a systematic way. In the exended phase space, the mass of black holes should be viewed as entheply. We derive the Joule-Thomson coefficient $μ$ explicitly, and with numerical method, we depict the inversion curves and isenthalpic curves with different parameter $J$ and $g$. It is found that there are only minimum inversion temperature but no maximum inversion temperture, and the ratio between minimum inversion temperature $T_{min}$ and critical temperature $T_C$ is a little greater than $1/2$, and increase with the nonlinear parameter $g$. Furthermore, the shapes of the isenthalpic curves are similar to most case studied before, we calculate the inversion point exists as long as the mass is no less than a certain value $M_{min}$, the effect of the parameter $g$ on the throttling process is also discussed.
